Per Reni (http://www.livingvictorian.com/askrenipm/askrenimar02.html): "The only information I have on Gerity Products, Inc. is a listing in the "Encyclopedia of American Silver Manufacturers," by Dorothy T. Rainwater and Judy Redfield, Schiffer Publishing Ltd., 1998, page 121. The company was (and maybe still is) based in Toledo, Ohio and advertised, "custom platers since 1898." Apparently, Gerity must have specialized in reproduction forms."
