So someone on craigslist is selling a couple of surface plates. They are from his father's estate and he says they are in good condition. So far so good. He has no documentation or knowledge of the manufacturer.
One is a basic 12x18x3 black granite, which seems normal enough. But the other is 12x18x0.75. I've never heard of a surface plate so thin and suspect that it is unlikely to be as stable as the 3" inch think version. But it will be much easier to move around the small area I have available. It also looks like it's two pieces bonded together horizontally. I wonder if someone was using it as a portable "good enough" plate. Even at that thickness it's probably a lot more accurate than anything I'm capable of.
I just wondered if anyone had ever run across such a thing. It comes in its own wooden box.
He's asking $45 for each one. Price isn't fabulous (assuming Grade B on the 3" version), but shipping is cheap since it's a 10 minute drive from home.
