The '55 3100 started off new in a local fire dept, the chief's personal truck I was told. There was some sort of instructions plate riveted to the glove box door, which was removed when it left the F.D.
Perhaps CA DMV had arrangements for assigning frame number VINs to local government vehicles? I rescued the truck from a field years later; the truck had been repainted by then but still has original red paint firewall.
Working on a photobucket account and I will post a couple of pix.
