I need some information on a Singer model 15. I saw a pretty blackside one, from 1942 in a cabinet. It needs to be rewired, and there's no needle clamp on the needle bar, so I can't even try it out by hand. The hand wheel moves very easily though. I'm thinking they want too much for it as it is priced $150 or $175. I was thinking that it was worth more in the $50 price range. Am I right, or completely off base? It is in a resale shop. Thanks for any info anyone wants to tell me either pro or against getting a 15. Don't know what the __ part of the 15 it is. Any help here? It isn't on e of the 3/4 machines like the 99, is it?
