Thank you, Mike Allen,? appreciate the download and the time to reply. I signed up to the site you mentioned and looked around, thank's, lots there. I found this on another site. It has the

Hello all, new here so I'm hoping this is getting sent to the right place. I just picked up a 1947 C9-10JR.Most of it is there and looks pretty decent, after a quick clean it seems like everything

Is this the label you’re looking for? mine is a 10K but I suspect the adjustment (and label ) is the same. Not in perfect condition, but readable. mine has V- belt from motor to counter shaft and

Still restoring my UMD 9 inch which I am converting to a 10K. The back side of the door that accesses the belt change area has an instruction label. If anyone has one that the label is decent would
