hello Omnitrac ,around 18900 model 60 were built by best and caterpillar from 1919 to 1931 ,if you post the number we can tell you the yr if it not on the list above ,bruce oz
The only number I can find is on the right side of the engine which has ENGINE 5470.
The right fender is missing so I assume that is where the tractor sr# was located.
Is there any way to determine a a tractor # using the engine #?
There is no numbers stamped into the frame up by the radiator.
