The engine number is the same as the tag....the number is on the righi side near the generator.....
Lets hope the engine hasent been chainged....Don

Engine serial numbers DO NOT MATCH on M's; many of the H's did match.
Use the casting codes to get within the month of when the parts were cast; when they were machined & installed would be later.

wayne is correct. you could get a good idea from the engine code.

Some do! I have a 1940 that matches. Its going to depend on how early of an M it is, and if the engine has ever been replaced. Look for casting codes, the only real way to tell. They will look like 12*7*K (One of mine, notice the day) 12 is the month, 7 is the day K is the year. (In this case 1941) I is 39, J is 40, K is 41, so on and so on........BTW the *s will look like screw heads

I looked under the generator and its BKM 110-200
which would make it a 1946...thanks all for help so far!
