Jim Carter truck parts sells the fiberglass grille. All COE trucks of this vintage were rated as 2 ton.
The engine will have a casting date that will read something like C 14 6. C is for march (3rd letter of alphabet, 3rd month) 14 is the day of the month and 6 is the last digit of the year the block was cast. In your case it would be 1946.
The cab is a modified conventional cab so corners, etc. are the same. If it has a rubber gasket for the back glass it is '42/'47 if the has a die-cast frame around the back glass, it is '40/'41. I think the lock in the passenger side door moved from the handle to a separate lock at the same time. 1941 had different park lamps/lenses. If it has a 2 speed rear axle, pre-war models shifted with a lever, later they used vacuum shift.
We have 5 of them in our family.
