Is J 05 Juki then? I like the green on the decals. You don't see a lot of green.
I'm working on a Happy made Montgomery Wards zigzag machine right now. I don't think it ever saw much use or oil. There's not a mark on it. It was frozen from dried oil but spins beautifully now. It's one of the smoothest running Japanese machines I've touched. That Juki should be as good or better.
