The seller has the website
http://www.sewalot.com/index.htm. It is a history of many vintage machines. It is so much fun. Full of beautiful pics and very interesting info. His is one of the 2 sites (only ones) that I found that had info on my Salter's Ideal Chain Stitch Hand Crank sewing machine. He has sold some exquisite machines on eBay lately. Check it out, you will be hooked, too.
