Welcome to the board. The most helpful people in the area of vintage machines hang out in the Vintage Sewing Machine Shop (VSMS.) We have our own section of the board, with nearly 1200 pages. Billy, (lostin51) is the fix and restore the machine guy, Glenn is the cabinet restore person, and there are a whole bunch of folks who must have all the bookmarks and knowledge combined to fill a library with information. This is our current page,
http://www.quiltingboard.com/t-43881-1167.htm. I spent weeks trying to date my fiddle base. The date is approximate, based on the cabinet style and the fact that it predates the thread guide for the bobbin. Be prepared to post some good pictures of your machine and any numbers you can find on it. I'll be watching for it.
