Looks like a teachers bell or a household bell. Would have had a handle in the top. Any markings on the inside lip?
Yeah... I am "staying" on the dates.
Bells are funky... they have not evolved much in hundreds of years.
They have been produced in mega-ness amounts and everywhere... and everyone with a bag of salt owned at least one it seems.
They have always been a "shot in the dark" on dating ones like yours.
No later than 1900 for sure I would bet though.
Hope I helped some.
