NOTE: Sid Lethbridge: aka Hook, maker unknown, mid 1880s. It is part of a small tilting pitcher set shown on page 109 of Pattern Glass Mugs by Mordock and Adams.
This set is based on the William Zimmer patent (below) of March 1884. There is a distinct possibility that this is Aetna's toy tilting pitcher because they were making a "patented tilting pitcher" in early 1884 and also a toy tilting pitcher.
American Pottery and Glass Reporter, May 8, 1884 - "The Aetna Glass and Manufacturing Co., Bellaire, Ohio, are getting out a new line of very handsome pressed and blown lamps; also a number of novelties, among them are the Butterfly Ice cream set, toy tilting pitchers, and several others which will be noticed further on."
