All basically the same truck, the one you see on the top of this page. WDX was the first one 1946-49?, then a B1,2, & then a C1,2 & 3, then W300M then WM300. Over time changes were made, biggest ones being a sychro gearbox sometime in the 50's and a 251 ci engine in the WM300 in the 60's. Model numbers and dates I mention are guestimates, somewhere on this site are a list of models and production dates.
