I have a early Holt 2 Ton that the serial number tag is missing, which I assume was orginally located below the seat as was done with the Cat 2 Ton, but there is no sign of rivets.

Does anyone know if the serial number was stamped in the frame in another location.

I have a engine serial number is there anyway htis can be used to determine the year.

Dennis, you are correct that the serial number plate was located under the seat the same as the Cat 2-Tons. It was however a smaller plate measuring 4" X 6" whereas the Cat 2-Ton plate was 5" X 8". I don't know if there is a way to determine date of manufacture from the engine number. My engine number is close to my serial number but not the same. One place you could look for a date is on top of the bell housing. You'll have to remove the fuel tank and the plate it sits on to see. Two of the Cat 2-Tons that I have, have a date in the casting at that location along with the part number. One is very clearly 9-11-26, and the other is ?-??-28 so I have to believe they are casting dates. The third one has the spot where the numbers were but they are not legible. My T-35 has no legible numbers there either but there is a spot that might have had numbers at one time. Hope this helps. Dave
