Here's forced translation of some info Wolfgang found on my behalf:
>>When the newly established Second Polish Republic temporarily took over the Danzig arsenal in the Free City of Danzig, the machinery there was moved to Warsaw and Radom (Fabryka Broni Łucznik) to establish its own arms production in the heartland.[21] Since the German machines were set up for the production of the Gewehr 98 and Karabiner 98A, Poland produced direct copies for the newly formed Polish army.[22] Because the Gewehr 98 proved too unwieldy in the Polish-Soviet War, a shorter rifle called the Karabiner 98 (K98) was developed. Like the German Karabiner 98b, the K98 is a version of the Gewehr 98, but with the length of the Karabiner 98AZ (later designated 'a'). The K98 from Warsaw had a straight bolt handle, while the variant from Radom had a bent one with a round knob.[23] The later developed Karabiner 29 (K29) is a direct copy of the Czech vz. 24 rifle.[23] Since the K29, which was introduced to all branches of the armed forces, did not meet the requirements of the Polish infantry, a weapon with a length of 1150 mm, the K98a, was introduced in 1934.<<
