I picked up a hand crank from a 1900 unit. It came from England and had the balance wheel included. I paid $105 w/shipping included and was glad to add it to the collection.
I also purchased the Chinese knockoff for a machine I sold for use in the field during re-enactments. The quality difference is amazing, yet the knockoff worked for the intendented application. I think the OEM unit makes 4 stitches per revolution. That way, for the purist, one will know how many stitches a given project takes
