Well, I just bought one at a thrift shop for $20. It's a "portable" with a cute little carrying case, even though it weighs a ton. Solid metal, motor on the back, beautiful -- gleaming silver and deep aqua blue. It purrs like a kitten and sews beautifully. Only problem is, I can't make it sew anything but a zig-zag machine. I've had ownership for about 30 minutes, so I'm not out of the game yet, LOL. I can't find any reference to a Jewel SM online. I did find one small reference in passing to a Jewel treadle, but..... this is definitely not treadle. It looks like new except for a couple of black marks that look like maybe somebody's grandbaby got hold of a Sharpie. It has a medallion that looks like a coat of arms with M on top left and W on bottom right. Montgomery Ward? I'll post a photo on my flickr.com site later tonight. I could not go off and leave this machine. Now, I'm not given to collecting machines. But this is the prettiest thing I've ever seen. And so clean. This was somebody's baby. Or maybe she didn't ever use it much. Tough to say. It's got several bobbins and that's all the "extras." A good friend is coming over in an hour and we're going to figure out how to run it. If anybody has any information about Jewel SMs please post.
