If the tag is missing check the edge of the block immediately above the gasket where the oil pan bolts to. Left side toward the front. The oldest engine I found this S/N stamping was a 1937 d13000. I don't know how early this process goes back. Good luck.
Our channel highlights machines from the earliest Holt and Best track-type tractors, equipment from the start of Caterpillar in 1925, up to units built in the mid-1960s.
