Never used one before, but if I come across it in the wild, I'll give it a go & report back.
Hello, folks, I would like to know if there's a "blue book" of sorts for vintage SR. From my research, it seems SR prices are all over the place....
Yes. I have a Shapton 12K & still use my black Ark, that I have lapped at 1500 one side, 2500 on the other, to finish.
