I have my grandmother's treadle - a Singer - 1907, I believe, but need to look it up. Although I have happy memories of her using it, I never have, and I've had it since 1976! hahaha... It's a decorative piece in my living room. It's a beautiful machine in a 3 drawer (each side) table. Reading all the posts here about actually Using them, has inspired me to try. It needs a new belt, for sure. Don't know what else. But when I'm ready (after the holidays) I will research it and try to figure it out. Wouldn't That be so fun? to sew on my gr'ma's treadle? hahahaha...
I have a bernina virtuosa 160 that I bought in 2000 (I keep saying it's a 180, but it Isn't! I'm such a dork.) I also have a featherweight from 1953.
