C4P Polish Heavy Artillery Half Track

The C4P artillery half track (Samochód półgąsienicowy wz. 34) was based on the Fiat 621 truck chassis licence-built by Polski Fiat in Poland. The C4P and Fiat 621 shared many parts but the gear box and front axle were modified to better suit the needs of the half track. The rear tracks were based on the Vickers E and Citoren Kegresse half tracks. The C4P was capable of towing the 120mm wz1878/09/31 gun although was also used for lighter 75mm Schneider and 100mm Skoda howitzers.
