I have a model 40h and i love it. Check Winkys workshop on youtube he has been working on one. Ian Matthews as well, and mine is on there under cyclebuster. On the top left of the knee elevation keyway you will find the model and serial number. Mine was made in April of 43, and sent to AC spark plugs in Saginaw Mi. Index is in Muskegon still, and they have every engineering drawing in stock, as well as some parts.
