Hoping for some help to figure out what this old farmall we have in the barn is. We want to restore it so went to look at the serial number but it is pretty much unreadable.The one from the side of the seat that is. The engine code reads 2-15-T. tranny reads 1-2-T. on the chassis under the seat it says 2-2-T and 351131-R something. So its been painted red poorly at some point as the belts, hose ,everything is red. But when we look close in spots where the paint is wearing off it looks white. Anyone help with how we can find out if it was originally white. Only numbers we can read on tag on side of seat is 1815 on the bottom and a 68 above it. Rest is gone. Thanks in advance. G
