I found one of these today at Goodwill for $30, but it doesn't have the footpedal or a bobbin. Does anyone know where I can find information on this machine? It looks to be a 1950's (at the latest) model.

There should be a model # on it. Even look under the machine. Sometimes they stamped them into the bottom of the machine. I also have a MW machine I'm trying to get info on. Mine is from the 30's in a cabinet. I know it was made by the National Sewing Machine Co. but badged MW. You might also try joining a yahoo group. Lots of info their. If you find the model # google it. Good luck.
