The item marked “Stratton England” and “995 948” is not solid gold. It’s cheap “gold tone”. Stratton was founded in 1860 as “Stratnoid”, initially making knitting needles. In 1920 they merged with Jarrett and Rainsford, to form “Jarrett, Rainsford and Laughton Ltd.", trading as “Stratton” and “Stratton of Mayfair.” In 1929, the company was headquartered at Alexandra Works, Kent Street, Birmingham, with London showrooms in Hamsell Street and Jewin Street.
Their main business was ladies’ compact cases but they also made lipstick tubes, trinket boxes, and costume jewellery, plus cufflinks, tie pins and such. Production was interrupted by the war when four of its five Birmingham factories were destroyed by bombing raids and they diverted to producing things for the war effort. By 1947, the company was operating from the Leominster Works, Lower Essex Street, Birmingham, and had London showrooms at Dean Street. The company changed hands several times before finally going out of business in 1997, but the “Stratton” name has since been resurrected under new ownership.
The number “995” has nothing to do with gold standards. It’s just the first part of a six digit Design Registration number. Registering a design is a form of copyright protection lasting for three years. I couldn’t find that particular number but I would expect a six-digit number beginning “995” to be post-war and I would estimate likely from the 1970s or thereabouts.
