Does it look something like this?

I believe this is a Pfaff frame for machine quilting. If you have both the frame and the carriage that goes on the frame, you can use any machine that fits the carriage. I think the Inspira was made for the Pfaff GrandQuilter machine, but you don't have to use that specific machine. What kind of machine are you thinking of using on the frame? Typically you want something with a 13" harp or greater.
