I am trying to figure out the serial numbers on a couple of Ford 2 ton (I think) trucks. Supposedly they are a 1938 and 1939. I have located the serial numbers on top of the frame rail, behind the LH front tire. Part of the numbers are clear to read and some not. The truck that I think is a '38 has a serial number of *BB18-4275039* OR it is *BBI8-4275039*. I can't tell if the 3rd digit is a 1 or an I. The '39 truck serial numbers are *99T-101256* OR it's *991-I0I256*. Once again it's hard to tell if they are an 1 or an I. Do all of the serial numbers of that era have letters in a certain position of the serial number? Also one truck has Ford 85 on the hood badge and the other has Ford 95. Are the 85 and 95 designations for the tonnage rating of the trucks? Any help would be greatly appreciated because there are no titles for the trucks and I need the correct serial numbers for the bills of sale.
