Can anyone tell me what this is?

Found this at an old colonial homesite. It's one inch long and 1/2 inch in diameter. It's solid brass with a hole all the way through. The inside of the hole is threaded.

Looks like a piston from a spool valve. Tony

Could be a couple for old oil or air line.

I think you may have nailed it. The site is a revolutionary war camp site. Thanks.

That T/C is a 20th century jag design. Revolutionary War era cleaning was with a tow worm or a button jab.

I think the piston idea was closer to the mark.

Ok thanks. It may be from a reinactment.

I'm thinking same as Tony & Charlie P... A hydraulic spool valve, plunger or pump piston of some kind, due to the o'ring groves on it. Could be a part from a hand drawn siphon pump to a hydraulic control valve on a farm tractor?

You may be right. Just googled spool valve and it does look like what I found. The site was also a working farm.
