I wanted to ask if in the Blueprint for Victory and Drive to Victory Books, if the last artillery tractor with a 7B3 body is listed?
It is difficult for me to know what date of the year 1945 its production is, according to the chassis number it could be from November 1945 or before July 1945.
I still have not found any with the dataplates that provide accurate data.
Thanks in advance!
