Found one that looks identical. My latest antique store find. Yes it was made in China, but for $40, I couldn't pass up its versatility. It looks as though it has had very little use, if any; the anvil has no marks, and the jaws are pristine - opens, closes smoothly - spins & locks down freely - jaws spin 360 deg smoothly & locks down when jaws are tight.
I was told on another forum that these Chinese vises are hit or miss - may take a beating and last forever or might break with the first beat down? We shall see.
