Here's my most recent 3/4 size machine. A SEWMOR VS. It's a copy of the Singer 128, and as best as I can tell uses the same size bobbins and shuttle as the Singers.

I've still got work to do on the case bottom and wee bit more cleaning, but she sews nicely and will fit into my SEWMOR collection well.

PS: I've really go to work on a less cluttered place to take pics. Sorry about that.
