Just curious about it.
The shop where I work has close to 150 years exp. and noone has ever seen one.
Could not find any ref. to it on the web.

I tried looking for any kind of resources on a comparator stand and couldn’t find much either. They are used just like a large SP except the beam is fasten to the plate. I use it for small parts and basic comparing Height, parallelism,etc.
