Designed in the 1930s, it was the basic tractor of Polish anti-aircraft artillery during the 1939 Nazi and Soviet invasion of Poland.

[2] In 1932 Janusz Łapuszewski and A. Schmidt of the BBTBP institute ("Armoured Forces Technical Study Bureau") designed a small, fully tracked artillery tractor based on TK-3 tankette.

[3][4][5][6][7] For heavier guns it was to be eventually replaced in Polish service with the PZInż 343 wheeled tractor, but only a couple of these were completed before the war.

In June and July the tests were resumed, this time with a 1,480 kg (3,260 lb) fuel trailer, and again in September, towing the new Bofors 40 mm gun (Polish designation wz.
