Welcome!! That is a COOL truck. Do you know the history? The front wheels look more modern with the larger diameter 10-stud circle.
Cool album of truck pictures too.

Thanks Frank!
Your 50 is pretty "Sweet" Too.
The truck from what I understand was bought in the mid fifties as a tractor with a broken frame.
A new replacement frame was purchased in the proper wheelbase and the wrecker body was installed.
The front axle is original(will check that further),the rear I'm not sure, as it has a Eaton electric two speed.
Need to research that too.
The aluminum Budd's are very early tube style,probably late sixties, early seventy's.
