A part of Germany's war indemnities was the provision of production data and plans of the Lanz-Bulldog.

Similar productions or also "copies" of the legendary Lanz-Bulldog are the 'Pampa Bulldog' in Argentina or the 'LE PERCHERON' in France.

The C-45 had a one-cylinder, two-stroke engine, with a maximum power of 33 kW (45 hp) and a cylinder capacity of 10,300 cc.

These changes included simplified operation, a more efficient fan, surface-hardened crankshaft, headlight, hydraulic lift, and starting gasoline fuel injection.

A metal frame was fixed to the windscreen, rear fenders were fitted, and a canvas cab was added.
