*5 cm x 3 cm. From Raventhorpe, Western Australia. Old Plummers label. Royal Ogden "Roy" Plummer was born in Missouri on December 31,1905, the son of Marjorie Farthing and Harry Lee Plummer, an electrical engineer for Western Union. Beginning in 1946, Roy (and his wife Winnifred Line, born 1911 and still alive at the age of 96, living in El Cajon, California) were the proprietors of Plummer's Minerals, advertising "choice crystallized specimens for advanced collectors." He sold worldwide minerals, and especially San Diego County pegmatite minerals, but also carried lapidary rough.Beginning in 1957 Plumm er sold small, carefully selected, styrofoam-mounted crystals and crystal groups measuring a half-inch square--what we would call small thumbnails today, but he called them "miniatures."Roy would often purchase specimens wholesale from other local dealers such as George Burnam (q.v.) and Russell Filer (q.v.), and also from local collectors such as Bob Winstead. The label would indicate 1952 - 1961 as purchase period.*-
