Beautiful heavy old tea set in the Sheffield plate style, silver over copper. The hallmarks are for Sheridan silver of Taunton Massachusetts, early 20th century vintage - probably 1920s.
This has a beautifully made tilt kettle teapot with stand and warming burner (about 13" tall overall), as well as a tall tea pot, coffee pot, cream and sugar, sugar cube or water pot.
It's been recently polished, and looks very good. There's no visible wear or damage to the silver, very little scratching overall. There's a little tarnished streaking to the insides of the lids, though the interiors look clean - I don't believe this set has seen much if any use in it's 100 year history!
