Thanks for the feedback. The auctioneer said it was an old plastic, which doesnt sound as glamorous as cellouloid or ivory! (tho I thought celluloid is what the old plastic was called.....) ho hum. It's lovelier in the flesh (in my opinion & in good condition). It's going into the auction with a 1930/1940 fur muff handbag with ornate metal hardware which is really lovely. It''s hard to part with them, but the bills need paying lol!
