My guess is an Early 1949. Not a 1947/48, not a 1949 late or later. My guess, it has an in the cab gas tank, rules out 1947/48. It had a thriftmaster emblem on the hood, making it an early 1949 and a chrome plated front emblem. Chrome grill rules out most 1951's or later. Bet it has an outside vent on the drivers side and the doors originally came without window vents.
