✅ SOLVED Looks like a bottle but sealed.

[Garscale]

I found this today an an old home site. Early 1900s house but was built on the rubble of an older burned home. Anyway its molded glass like a bottle but is totally sealed. No markings of any kind. The only guess I have is some kind of radio tube?

Cool, specialized, I'd say....
Haven't seen any of the like, on the shelves of yesteryear.

I believe that's the plunger from a re-usable glass syringe. A flexible grommet fits over the end to create a seal in the syringe barrel chamber.

Red Coat never disappoints. That looks right.

Any other opinions?

I have an opinion
That redcoat is very extraordinary. I always look at a thread if I c that he has replied.

I dug around the net a bit and found some plungers identical . Great job RedCoat. This one is solved.

Great ID, Red-Coat.

It looks like they are still available for a variety of uses.

Garscale, do you use your mechanical screening device on house sites too? I've wondered about that. I sure could use something like that. It might beat detecting. Gary
