The Armistice that ended World War One saw the re-emergence of the Polish state after more than 100 years of domination by powers including Prussia, Russia, Germany, and Austria.  The military charged with defending the nascent state found itself equipped with a collection of weapons that was eclectic to say the least.  The light machinegun inventory was no exception to this situation.  There were Lewis guns, Bergmann MG15na's, Madsens, Chauchats, and Maxims.  It was decided that that a new light machinegun would be chosen by the army with which to replace all the disparate and obsolescent types.

(Note:  The Polish Army observed a distinction between types of light machineguns, and this distinction can be noted in the nomenclature assigned to the different models.  Lekki karabin maszynowy or LKM, literally translates to light machine gun, and refers to a lightened version of a belt fed machinegun.  A prime (but not Polish) example of this would be the Browning M1919A6.  Alternatively, reczny karabin maszynowy or RKM, which translates to hand held machine gun, refers to magazine fed machine rifles or light machineguns such as the Bren or the BAR.  This method of classification based on feed system was maintained until the beginning of World War Two.)

Meanwhile, back in Warsaw the frantic search for a new light machinegun continued. . .  The Polish Army created a board of officers charged with organizing a competition to choose a new light support weapon.  The board held the first round of competitions in July, 1924.  The entrants included the Lewis, Madsen, Benèt-Merciè, the Hotchkiss Model 1922, and three versions of the Browning Automatic Rifle (BAR):  the US M1918, the Fabrique Nationale Modèle 1922 (which was actually made by Colt), and the US M1922 Cavalry Machine Rifle.  Despite the number of well qualified entries, the initial competition concluded with no clear winner, and the Board declined to accept any of the guns submitted.  Another round of competition was therefore scheduled for January and February 1925.  This next round featured more entrants, including the Madsen wz.24 (NB: The Polish word for model is "Wzor" and is abbreviated "wz."), the Beardmore-Farquhar wz.24, the French Lewis wz.23, the Chatellerault wz.24, the Hotchkiss wz.23 - Model 1922, the Italian ALA wz.24, a Swiss Furrer wz.25, and two commercial BAR's - wz.24, one with a 500mm barrel and one with a 600mm barrel.  The BAR's were actually Colt produced, inch pattern guns supplied to FN under earlier agreements between the two companies.
 
The competition was overseen by the commandant of the Central Shooting School in Torun, Colonel Tadeusz Felsztyn.   Under his watchful eye, the field was narrowed to three entrants:  The FN supplied BAR, the Hotchkiss  Model 1922, and the French Lewis.  Of
FN Model 1924

these three finalists, the Model 1924 BAR was ultimately chosen, adoption dependent on eleven modifications to support the Polish Army's unique needs.  Specifically:

There were some significant deviations from the BAR as used by the United States during the First World War, most notably the repositioning of the recoil spring to a tunnel in the butt.  Despite the selection of the FN Model 1924 as the Polish Army's new light support gun in 1925, it took almost two more years for a contract to be let.  Finally on December 10, 1927, Fabrique Nationale and the Government of Poland signed an agreement for 10,000 guns to be completed by the end of September 1929.  Part of the agreement was a license for the Poles to begin licensed domestic production of the new gun, now designated the wz.28, at the Panstwowa Fabryka Karabinow (PFK, or State Rifle Factory) in Warsaw.  To speed things along at FN, a Polish design team was sent to Herstal to assist in making the requested modifications as well as to study FN's production methods with an eye towards avoiding as many of the Belgians' mistakes when production was undertaken in Poland.

As with the other BAR variants, the wz.28 is a gas operated, locked breech air cooled autoloader.  As the bullet travels down the barrel, it passes a gas port.  A small portion of the propellant gas is tapped off and used to propel the gas piston to the rear.  As the gas piston moves rearward, it carries the a slide with it.  As the
slide moves back, it pivots a link forward and down, which in turn carries the bolt lock down out of engagement with the receiver's locking recess.  At this time, the slide is free to carry the bolt to the rear, said rearward motion extracting and ejecting the spent casing, and cocking the hammer.  The entire system is then pushed forward again by the action of the recoil spring.  Forward motion of the bolt allows it to strip another cartridge into the chamber and then lock up once more.

Despite FN's industrial prowess, the Belgians soon came to the rather unpleasant realization that manufacturing the BAR was a significantly more difficult and more complex task than making Mauser style bolt action rifles.  As a result, the contract experienced delays and the first shipment of 8,500 wz.28's was not delivered until November 1929, and the final 1,500 in February 1930.  Initial license production in Poland didn't fare much better.  To begin with, the Belgians sent the Poles only part of the necessary production documentation, and the documentation supplied was the original Colt inch measurement drawings.  It is likely that this was done because the Belgians themselves either lacked a finalized set of production documents or did not believe that their initial metric conversion documentation was good enough to work from.  Indeed, it was later discovered in Poland that the initial deliveries from Belgium were not fully interchangeable, and had to be refitted and rebuilt at the PFK.

The Poles were justifiably angered at this perceived slight.  All commercial connections with FN were severed, despite the entire payment having been already made.  The Polish design team was withdrawn, and engineers Jurek, Skrzypinski, Przybylkowski, and Wasiliew were assigned to draw up a new set of metric blueprints.  These activities were delayed by FN's application for a Polish patent on the improvements which had been proposed by the Polish design team while working in Herstal between 1928 and 1929.  Despite these obstacles, and the impediments attendant to the FN contract, domestic production of the wz.28 at the PFK got under way in 1930.

Wz.28 production was to continue, uninterrupted until Poland fell to the Nazis in 1939.  All wz.28's, regardless of whether they were eventually exported, issued to police or to border troops, were accepted by the Polish Army, and are marked accordingly.  Production totals for wz.28's accepted by the Polish Army are as follows:
 

1930
600
1931
2,400
1932
860
1933
1,355
1934
1,550
1935
1,500
1936
580
1937
900
1938
900
1939
315

Polish stores of wz.28's included 13,009 in 1934, 17,115 in 1936, and 19,971 in 1938.  While production got underway, the Belgian made guns had been issued to the ninety first-line infantry and cavalry regiments of the Polish Army.  First to receive the wz.28's were the elite Lancer formations, who turned in their old Maxim MG08/15's in March 1930's.  Issue of a light machinegun to cavalry units caused its own problems.  Mounted Polish BAR men complained that the wz.28, which was more than twice as heavy as the issue Mauser rifle, was too bulky to be strapped across the saddle, and thus had to be carried slung diagonally across the back where it caused spinal injuries while riding.  As a result, a carrying rig was perfected in 1931, and adopted in 1932, with a total of 462 being ordered.  The carrier consisted of a strengthened action cover fitted with rucksack type double shoulder straps that centered the gun behind the riders' backs.
 
In 1935, an improved variant of the wz.28 was introduced.  Second variation wz.28's are all fitted with the distinctive anti-aircraft ring sight base on the barrel, possessed a large diameter front sight guard, a smaller battle-sight notch, a reshaped butt with a prominent "fish-tail" contour, a large flash hider, and a reinforced gas  Late Model Wz.28

cylinder attachment.  A special anti-aircraft conversion kit was issued with most wz.28's, consisting of the anti-aircraft ring sight, the anti-aircraft peep sight, and an oversized gas cylinder tube cross pin assembly which served as an axis for the anti-aircraft fork mount.

Further modifications were planned for introduction in 1940, but these were overtaken by events, specifically the Nazi invasion in September 1939.  These modifications included a folding buttplate like that found on the US M1918A2 BAR, a reinforced bipod with wider skids and stake holes, a muzzle compensator, and a quick change barrel.  These modifications were introduced in the prototype wz.28/38B and the wz.28/38T, which underwent trials in December 1938.

The wz.28 saw considerable action during the 1930's, albeit not in Polish hands.  A number of wz.28's, along with Chauchat machine rifles, ammunition, grenades, powder, artillery shells, and a variety of other munitions, were covertly sold to the Spanish Republican government, and used during the Spanish Civil War.  An initial shipment of 200 gun was sent on September 9, 1936 through the agency of E. Grimard of Paris, allegedly destined for the Mexican Legation  in Paris.  This was followed by another 100 guns on October 7, 1936, also through E. Grimard,and also allegedly for the Mexicans.  A further 225 wz.28's were shipped on July 31, 1937 through M. Wolf, supposedly destined for the Greek Consulate in Gydania, Estonia.

Wz.28's were also issued to the embryonic armored formations on the basis of one gun per TK-3 or TKS (the TK-3 and TKS were more akin to Bren gun carriers than tanks) as secondary anti-aircraft armament.  Due to the financial exigencies of the Great Depression, all units were not re-equipped until the late 1930's.

During the short-lived Polish resistance to the Nazi invasion, the RKM wz.28 proved to be an effective and well-liked weapon.  They also served with great effectiveness with resistance organizations and later during the late 1940's civil war against the communist backed regime.  However, there was other important users of the wz.28.

It is often said that imitation is the most sincere form of flattery.  If that is the case, then wholesale adoption must be flattery of the highest sort.  Many wz.28's captured from the Polish Army were used by Nazi forces under the designation lMG28(p) and later lMG154(p).  The lMG154(p) had two variations, the lMG154/1(p) being the earlier version of the wz.28 and the lMG154/2(p) being the later.  The captured wz.28's were issued to German combat formations for use as automatic rifles rather than as true light machine guns.  They were later replaced by Gewehr 41's and captured Soviet SVT38 and SVT40's.   Other wz.28's were used by the Soviet forces who occupied the eastern half of Poland in 1939.  In a widely publicized Soviet newsreel, Soviet troops are shown on parade in Red Square in October 1941, on their way into battle.  Among those taking part are formations made up of Moscow's workers.  They carry former Polish Berthier rifles and wz.28's.
