Maybe to get tube out of caulk gun.

Could be a caliper set for a certain purpose/situation.
Or it looks like it might be part of a drain.
Sorry, that's about all I can come up with.

I was Plumber back in the 80's - it was my parents family business .
they bought Ken Prentice Plumbing & Heating in Damariscotta , Maine in 1976 . It went on to become Mid Coast Energy Systems . I am going to bring his birthday present to him tomorrow - He is 82 - I will bring the tool .

it looks like a water heater thermostat / heat control wrench.

some kind of pin wrench for a specific use, it looks to me like a proprietary tool that came with a kit, and was only meant for that one thing. I've seen other types of pin wrenches that were single use specific, but never the one you have as far as I know.

My Father does not think it's a plumbing tool - My girlfriend thinks it's a dental tool .

Maybe it's for pulling out stuck dentures?

I can't find a match to your sanitary drain pliers, but here are some modern ones showing how they were used.
