A wonderful craftsman made heavy gauge copper container or canister.

Found in a lead workers / plumbers tool kit, possibly an apprentice piece due to the variety of related trade skills used in its manufacture and the resulting useful object.

The pictures provide a far better description that any we can write.

Flared top and bottom with threaded solid brass cap and an almost invisible soldered joint to the base.

⁷/₈ inch (22mm) diameter opening, 12¹/₄" (310mm) overall length excluding the raised lugs on the brass cap.

Please see all images.
