1958-60 Ford C-Series would be my first thought.



Not a Chrysler product. That insignia suggests that it's a Nash.



This is a Chrysler product though; A 1954 Plymouth.


And yes, this is a 1955-56 Dodge.


But this isn't a Dodge. It's a 1957-60 Ford F-Series, anywhere between an F-800 to an F-950, or F-8000 to F-9500 if it's diesel powered.


This one's either a 1948-54 Chevy 6100, or a GMC from the same period with the same GVW's.
