[Chaznsc]

Helping a good friend sort thru some tools, an you help me ID this one? (More will follow)

 

[G_P]

Is that solid or hollow? If hollow it could be a sight glass of some kind?

Sent via carrier pigeon.

 

[Outlawmws]

It might help if the pic didn't cut the ends off.

 

[Dale B]

If both ends are the same I'm gonna say a manometer of some kind...

 

[trout]

giant eye dropper?

need better pics of the ends.

 

[neophyte]

Is that supposed to hold a fluorescent tube?

 

[ArcStyles]

Something for a fish aquarium perhaps.

 

[Matrazzo]

battery acid tester possibly?

 

[Matrazzo]

Didn't realize how big it was now I feel dumb for my answer

 

[Chaznsc]

I put my eyes on it tonight. It's 30 inches long, solid glass with metal caps on each end. Looks like and insulator of some kind. It weighs 30 pounds or so.

 

[Zeke]

Could be used as a water level.

I would agree with an insulator or spacer for high voltage use. Probably kept the phases apart. Could also have been for very high power radio transmitters, when wire antenna were more common than towers.
