C2P
type of artillery tractor
C2P was a Polish light artillery tractor. Designed in the 1930s, it was the basic tractor of Polish anti-aircraft artillery during the 1939 Nazi and Soviet invasion of Poland. There are only two surviving vehicles, both in private hands in Poland.
Development
The origins of the design can be traced to the Carden Loyd tankette of the 1920s. In 1929 Poland bought 10 or 11 Mark VI tankettes with a licence for their production, and used them for development of their own TK tankette series. In October 1931 Polish General Staff expressed interest in a small, highly mobile artillery tractor intended for 75 mm field guns in Polish service at the time. 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. It was designed to tow 40 mm Bofors anti-aircraft guns, but could also tow other light and medium artillery used by the Polish Army, such as the modernised 75 mm Schneider guns and 100 mm Skoda howitzers. 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.
Initially designated C2T (Ciągnik 2-tonowy, "Trailer, 2-Tonne"), the design looked promising and the following year the first prototype was constructed by the PZInż works.
Begin with the source’s own compact description: “C2P” is type of artillery tractor. The dossier treats that line as a proposition to test through type, artillery and tractor, not as a finished interpretation.
Why this record matters
The phrase “type of artillery tractor” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Nov 1, 2025. The linked authority identifier is Q750106. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1939, 1929, 1931 and 1932.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
