An older friend of mine is having to replace his shed after 50+ years and has gifted me the clamp shown below. He said that he probably wouldn't use it for its intended purpose again but that I might.
I gratefully accepted but haven't a clue what its specific purpose is. I can see lots of possible uses but is there a specific use anyone knows of?
Any ideas?

Welding clamp if I had to guess.
It’s an edge clamp (sometimes called a moulding clamp) For clamping a strip of wood to the edge of a piece of plywood for instance
Gluing veneer to the edge of a sheet of wood?
It's a boaby clamp.
For edging as above.
Nice. I'm sure it could be bastardised into so much more....
If you get another they can be used to hold mitres in place. I used to use them on curved work to glue the edge trim on faced ply
Okay. We are going for edging clamp on this one.
Tomorrow I will bring in the other thing I got and see if we can identify that. It has a dial and a probe thing so seems to measure distances but any more insight would be welcome
The chap who has given them to me seems to think I know exactly what these things are for and have served the same engineering / stone carving / electrical engineering / artistry stuff that he has so won't insult me with explanations. This is mostly fine but every now and then I am stumped.

I have a strap clamp which does similar. There are 90 degree ends to hold it in place and then the strap holds the edging in place. Given that rubber strap has been around for a while I didn't think of this three point clamp as something for that task.

Kayak - I just need a few more then...
I have used stretched plastic insulation tape when I have had to clamp like that. Now I have the proper clamp. I feel un-neutered
It has a dial and a probe thing...
Without even seeing it, that sounds like a DTI, or Dial Test Indicator. It's for really accurate measurements of things like shaft ovality, whip, (bend in a shaft leading to running off true) or shaft alignment across couplings. Very useful...
... in the right circumstances.
DTI gets my vote too.

He was lead engineer where they used to manufacture industrial lathes so that sounds about right and aligns with my thinking
With later Land Rover Defenders you have to use a dial gauge to set the wheel bearing end float. There are different sized spacers you swap until you get just the right amount of float. Effing annoying when what it used to be was a nut and locknut - you just tightened it up until it just started binding, then slackened quarter turn and tightened the locknut.
I do like a clamp identification thread.
The main problem with clamps though, is you never have enough,and they arent usually cheap. Even the ones in Kayaks pic at a tenner each. Those ones are at the start of the price range.

Very handy to have, so don't ever get rid of it.
With any luck it's a dial indicator ... attached to a professional wheel truing stand.
Well, you never know.
Hmm I also thought it was an edge clamp but that one would be a pain in the hoop to use because you can't place the edge clamping thread where you need it.

Good point.
It's a bit rubbish in that sense.
Sorry WCA 😔
What's this one originally for then?
I use it to hang up my Bluetooth headphones but I'm not sure it was originally designed for that.

That's a jewelers vice.
Holds a ring so you can hold it tightly.
Well I say jewellers vice.. It's a hand ice but I have only seen jewellers use one.
I suppose it would be handy for more especially polishing on a wheel.
Yes. It's very handy actually, beyond hanging headphones up. 😊

On the other hand, I would want to put wooden packs to protect the surfaces, rather than clamp directly, and that clamp guarantees against not bothering to.
Woid packers are a given but ivd have each clamp set up and ready to go before glueing commences and a weird stack of shims with add faff for every clamp you had to do.
