There are several sites on the web that sell old sewing machine manuals. Do a Google search. I've never heard of the brand & I have owned lots of older machines. Singer has a site (for their machines) where you can get info. I'd suggest calling around & see if you can find an old-timer who runs a "ma & pa" sewing machine repair business. Or send a photo into the people who sell the manuals for old machines. There are many collectors out there, but I don't know how to find them.
