help identifying antique air vent

Can anyone identify this air vent?? Probably very early. No identifying marks or logos at all.It came along with 17 radiators stored in a basement.

Ain't that special!

Is it made out of brass?

the vent is brass or bronze

Yes, brass or bronze. casting marks lengthwise through the C/L of the nipple.

The adjustable pin will meet a pin that could extend from the body (on pressure or temperature  -  haven't put it in a radiator or pot of boiling water yet.)

That's a new one on me

obviously some sort of adjustable vent. Might be a Norwall or Libra or similar- the adjuster probably points up when the vent is installed, and water sits in the body of the vent all the time.

I know I have a photo of them some where

I just need to find which old parts book it is in. Walworth may be close. I do not see ones with the adjustment screw but the bodies look close.

Do you have photos of the radiators?

and what region they are from.
