Sigma Koki steel linear stage, 60mmx60mm, M4 thread, 13mm mic travel, VGC

Description

I acquired this linear stage, a goniometer, and a rotation stage maybe 6 years ago, and I thought I would have some use for them eventually, but I haven't, so now I'm interested in finding a good home for this stage (I've sold the goniometer and the rotation stage that I listed separately). The stage is mostly hardened steel (it attracts a magnet) with what they refer to as a black chrome finish, but the bottom plate is aluminum with a black anodized finish. The stage is in fine shape cosmetically and functionally.
You can visit Sigma Koki's site (sigma-koki.com) and find lots of info. about the company and their products (they have an English version of the site there). This model of linear stage isn't on their site, so it might be a discontinued model, as the micrometer holder on this one is different from what they show for similar linear stages on their site.
The micrometer has 13mm of travel. The threaded mounting holes on the top platform are M4 thread and are spaced 50mm center to center at the corners, with 25mm center to center between the center mounting holes and each corner hole. The height of the stage is 25mm.
Please feel free to ask any questions you might have, and thanks much for looking.
