Yea! A nice 15-91!! love those machines!
That is the same model machine and cabinet that I picked up not long ago that came with the really neat attachments. My desk has the foot control built into the bottom of the drawer stack, and has a little lever that you step on to control the machine. It's a very substantial desk. Did you get a stool to go with it? I love the little hinges that you have to flip up to get the drawers out. I just cleaned mine up a bit so I can put a machine in it today. Will refinish it at some point . . .
If you need any parts, the machine I got is dedicated as a donor machine.
