Hey guys... I got a couple of questions. Hopefully not too stupid. I've got a 1949 1 ton I'm restoring, or I've been told it's a 1 ton.(Maybe a 3/4 ton) There are no decals or emblams stating 3100, 3600, etc. I've tried decoding the serial number, but my serial number is all numbers (no letters) and won't work with any of the decoding sites I've found. The truck was built in Canada... if that matters. The original aluminum serial number plate is still riveted to the door post. I also found what appears to be a tire inflater behind the seat. Looks like it screws into a spark plug hole...? I've been told this is something that came with the truck. Is this true? Thanks for the help guys!
