Looks solid. I believe it has 6 lug wheels which would indicate it’s a half ton. Wing windows were standard in ‘51, so it is a ‘50 or earlier. I think the doors are interchangeable with your ‘53 if you would want to retain them.

I don't think it's a '50 as the firewall is different, so '47-'49. That means it will have knee action shocks.
The one Dan found in South Dakota will have tube shocks which will be a lot less work when swapping things around. No need to weld on new mounts for tubes.
