From production start in late 1940, until replacement by the ​³⁄₄-ton models in 1942, the G-505 half-ton, 4WD, Dodge WC models evolved from the VC series, through no less than three mechanical engineering versions – T-207, T-211, and T-215 – in no more than a year and a half; while receiving the T-215 specification engine midway production of the T-211 coded versions.
Half-ton rated WC series models were numbered, roughly chronologically, in the WC-1 to WC-50 range, but skipping numbers WC-2, WC-28 to WC-35, and WC-44 to WC-46.

Based on Chrysler Corporation Mopar's 1946 annual model chart and serial number guide, the distribution across the versions was: 
31,935 units of the WC-1 through WC-11 models, with the T-207 engineering code and a 217.7 cu in (3,567 cm³) engine with 85 HP;
17,293 units of the WC-12 through WC-20 models, with the T-211 engineering code and initially the same engine, however during August 1941 the T211 engine was increased to 230.2 cu in (3,772 cm³) and 92 HP, but the overall T-code number was not changed on affected models (e.g. WC-18)  
28,537 units of the WC-21 through WC-27 and WC-40 through WC-43 model, with the T-215 engineering code and a 230.2 cu in (3,772 cm³) engine with 92 HP.

T-207 range units initially received only front axles with Bendix-Weiss constant-velocity joints, whereas T-211 and T-215 models were either given front axles made by Bendix or with Rzeppa design CV joints, made by Ford.
Additionally, from the T-211 onwards, the rear brakes were 14-inch instead of 11-inch drums, and on the T-215 a military instead of a civilian design dash panel, with round instead of square gauges was introduced.
Among the T-211 range versions, no single WC model number was explicitly used for any winch equipped units.

Aside from the above, another 1,542 rear-wheel drive units (engineering code T-112) were built (WC-36 through WC-39, and WC-47 through WC-50 — mostly carry-alls and pick-ups), that retained civilian bodywork and front axles (one-ton on-road rating).

Common specifications of the 1/2 ton WC trucks were:
Drive: four-wheel drive — except for WC-36 to WC-39 and WC-47 to WC-50
Wheelbase: 116 in (295 cm) – both on four-wheel and two-wheel drive models
except 123 in (312 cm) for ambulances and phone line / emergency repair trucks
Track width: 59 ³⁄₈ in (151 cm) front — 61 ³⁄₈ in (156 cm) rear
except 55 ³⁄₄ in (142 cm) front track on rear-wheel drive models
Tires: 7.50x16
Brakes: Hydraulic
Engine: 6 cyl, in-line, L-head
Transmission: 4 forward/1 reverse, manual
Transfer case: Single speed
