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).
Oh, and I should mention, I picked this machine up at the local Goodwill during their Monday $1.29 pink tag sale. Anything with a pink tag was $1.29, and this machine happened to have one. Yep, less than two bucks for this sewing machine and case. I went to the store after work too (5 or 6 at night), so apparently it's a machine that not many people yearn for. I'll discuss that a little later though.
Here's a fuzzy photo of the foot control. It has a slider for SLOW-FAST adjustment.
The 'buttonhole' knob has a crack in it. I've since glued it together but don't know how well it will hold up. The stitch length lever on this machine (and others of the same vintage) seem to be out of place with their industrial look. All other knobs are nice looking but the stitch length lever just seems out of place, like its plastic handle is missing.
The (old-fashioned) familiar Singer stitch length lever, plus an on/off switch.
Forgive the shavings. I didn't take time to clean up the machine prior to photographing it. The serial number on the tag below is the same as is stamped into the underside of the frame.
The stitch selector mechanism is quite similar to a Singer 401 and 500 but those machines use steel gears and steel cam plates, where this 630 uses plastic/nylon. It's still a fine machine though, and works very well.
