Description: rhodium plated base metal, rhinestones, enamelling

Reference: Schiffer, Fun Jewelry, p. 55. Brunialti, American Costume Jewelry - Art and Industry (2008) Vol 1 p 106. Patent is reproduced below (scroll down); designer Gene Verrecchio, dated 1942. The original duette mechanism was patented in the US in 1930-31, then by Coro in Britain in 1933-34 (No. 410,496), but the Canadian duette utility patent has yet to be located. Coro design patented many pieces in Canada from 1945 to 1947 (all duplicates of US patents) - but apparently none before, and very few after, those dates.
