I recently spent 8 months restoring a Free No. 5 sewing machine, complete cabinet and mechanical, that is fully operable. I wonder if there is a market for such a machine? Please advise

Can't help with the value, here's the Manual:
Free Westinghouse ALB #5 Sewing Machine Owner Manual M - eBay (item 200300742015 end time May-19-09 08:59:29 PDT)

Amish and menonites may be very interested since they generally do not use electricity.

How did you get the actual sewing machine out?
