Thanks much, mhooper, here is what is stamped into the top of the vertical knee way: 40 H 3300
I have been told that this is both the model and serial number with the "40 H" part known as the model and the "3300", part apparently my machine's serial number?? But I am so green on this that I don't know if this information is correct or not. Thanks for any help you can give on it.
