The title says it all. Ok, so maybe it doesn't, but we do know from Singer's name for this machine that it does zig zag stitches. What we don't know until we delve into it is that it has an electronic motor control, which has an automatic needle-up park feature. That's kind of cool. And it has very similar stitch controls to the much-revered Singer 401/500 series. And it has a built-in bobbin winding feature. You simply leave the bobbin in the machine, flip a lever, hit the gas, and don't let up until the bobbin is full. But enough of this. On to the photos, which by the way, were taken before I did anything to clean up the machine.
The carrying case leaves a little to be desired. Instead of gluing down the loose flaps, someone decided it was easier to just rip off the offending flaps. Bummer. But the big S is still proudly displayed.
This is what a 630 looks like. It's got a metal main case and top lid (cast aluminum or pot metal of some sort).
