Old Glass Cap?

[ronea2]

Found near late 1800’s mining town home sites. One side partially flat and thick glass. Bottom is recessed. (Sorry couldn’t figure out how to rotate photo.)

Thanks for the help.

Sight glass for old pump type oiler. "not drip type"

Hadn’t thought of that. I’ll see if I can find a photo one.

I'm thinking the top to a coffee percolator.
.... but then I'm not a big coffee drinker.

The older Manzel and Madison Kipp were the brands I had in mind.

Hadn’t thought of that. I’ll see if I can find a photo one.

Coffee Pott glass from lid

Could be from a coffee pot lid. Haven't been able to find one on the internet that matches.

Fuel filter bowl from old tractor? What does the bottom look like?

I don't think this is a coffee percolator sight glass (2nd pic), otherwise it would be perfectly round.

Looks to be industrial made, as tony already suggested, maybe an antique gas pump sight glass (1st pic).

Looks to be mold press made, also has imperfections in the glass, likely dates to the early 1900s.

Maybe a sediment bowl from a tractor fuel shutoff. Here's one from a Ford 8N...1940's. Gary
