Well I don't know! But from what I can tell most of the Trucks in the Gallery have straight metal across the tops of the doors. Now most of these are 1 1/2 ton trucks too.
Sorry I could be of more help.
(edit) After posting this I did some more looking and I think this looks more like a 35 Chevy. But once again I am no expert.
good luck and let us know when you do get it ID'd
