I picked up this interesting tool but I need help in figuring out what it is. I have faith that someone out there can ID it.

At first I was going to say a plumb bob for a transit, but since the pic shows points on each end, I'm not thinking that now. The end that had the knob, well either end....does the points move at all up or down?

Also, what is where the two screws are? Do they adjust or do they hold another part on?

Looks like a fixture from a test instrument, not a typical hand tool. With pointy things on it I might guess hardness of some sort? 'Course that wouldn't normally put pointy things on three ends, but maybe force from the top plunger is transmitted through the material being tested and the force is measured at the bottom -- through a part missing that attaches it to a balance or scale of some sort.

Not the same as yours, of course, but in the way of example here's the Emerson Dusting Tester, used for measuring lint on rolls of paper by pressing a black felt against the roll.

For the OP....if you can't figure it out and don't want it, I'll give you a $10 for it and polish it up for my shelf. :thumbup:

I have a plumb bob on a string, and I had it wrapped around my shelf and hanging down. A friend was over and asked me what that was. He had never saw a plumb bob before :wtf:, so I told him it was to detect earthquakes. It couldn't have happened any better if I had begged for it, but no sooner than I said that, the plumb bob moved. He looked at it with the funniest look I ever saw. On the late news that night, it was reported that there was an earthquake in Kentucky and felt all the way up in Ohio :lol_hitti:lol_hitti:lol_hitti

This had me curious enough to keep searching until I found something. After some random Googling one of my guesses was some kind of gyroscope or balancing or testing tool for clock springs. Turns out I had at least ventured into the right neighborhood.

"This is an escapement maker's uprighting tool. It is used to get a pair of holes lined up in the top and bottom plate of a watch. In use, the bottom plate has a pilot hole or a punch mark is already in place. The watch plate is placed flat on the table and the lower sliding center is moved up to fit in this hole. The upper plate or bridge without a hole is attached to the bottom plate. The top runner of the tool is then lowered and the sharp center marks the bridge for drilling."

Is this one of those contests where "If you can guess what it is you can have it? :D

You are awesome. I knew there would be some here that could figure it out. It was puzzling me to no end. Thanks again.
