The US prefix was FBKM for a farmall M engine, all the US 6 series engines I can think of ended with the last 2 letters KM except 0S6, which ended with SM if I remember correct. Don't think all early production engines were coded with the standard code, but have no solid evidence on that. Some early US M tractors didn't have a serial # plate, if the tractor is a early one try to find a number stamped in the frame rails.
For a US 6 series engine look for a block casting # above the oil filter, that # and suffix letters may help narrow it down. May be able to find a date code on the block about the same level as the cast number, but looking on toward the front. Just asking in case you have a C type engine, is the engine governor on the right or left side of engine?
US M with that low engine serial # would probably match the chassis serial # or be very close, unless you can find date codes on chassis and engine and can determain nothing was changed over the years, that would still be speculation.
