Hmm , funny thing is my MWG has number 1423 , so MWG`s were only made under the first contract ? only 50 units are supposed to be made . My MWD has number 3116 , and according to Vauxhall it was produced in November 1939 ( replied by them in 1984, when they even send me a lot of factory pictures from wartime Bedfords) Body has plate on it with 1939 , but no contract or WD number stamped in it .Long time ago We (Bart Vanderveen and myself)tried to figure out Chassis numbers from the various Bedford types , but numbers jumped sometimes with 50 to 130 numbers up , and later down , so we gave up in the end , Vauxhall only had months on the delivery charts , so you could look up a chassis number , and they could tell you which month it was deliverred, maybe it has to do with the external body manufacturers.
