That makes sense. The indicator is a little stiff. Thanks for the offer. I have others for the same purpose so I won't need your part. Thanks again.The clamps are probably dedicated tooling for some specific task. I don't recall seeing anything like them in standard tooling.
The indicator is a Last Word by Starrett, but it appears to have the contact point missing. I believe I have one I can send you if that is the case. It isn't a special gage, but a standard DTI. Some people love them, others not so much. I'm in the latter group.
Thanks.In your top left pic, those are key seat clamps, like Starrett #298.
Bottom right is an edge finder. They were made by Moore in Bridgeport Ct. There are many copies.
