Janey is a whiz at finding stuff on the internet. I'm kind of waiting around for her to post.
Meanwhile, I'll share how I've found manuals in the past. As many sewing machine companies, post WWII, sold their machines to many different sellers. For instance, you might find the same machine labeled Kenmore (sold by Sears), White (sold by independent dealers) and Gritzner (mostly sold in Europe). Most department stores had machines with their name on them (called a badged machine). So, you search (by hand, not Google) by the drawing of the machine on sites that sell multiple manuals for download. I put the machine in front of me or a photo of the machine and go searching.
