WC-3 WC-13 WC-21 Truck, 1/2 ton, 4x4 Dodge WC Open Cab Pickup w/o Winch (G505)
The Dodge WC-3 and the very similar WC-13 and WC-21, are 1/2 ton pickup trucks with slightly different engines and other small differences. All have an open cab, flat face cowl with express body and transverse seats but no winch. They are closely related to the WC-4 and WC-22 which differ by having a winch and a longer frame to accomodate it. All are part of the WC model series G-505, built by Dodge during 1941 or early 1942.
If you don't have the vehicle dataplate, to differentiate you must know the U.S. Government registration number (Army number on the hood) or the serial number which can be found stamped on the left front frame.
