Yesterday my son and I visited his great grandmother (from his father's side) and she gave me this lovely duck handle. Which I presume is made from celluloid, an early type of plastic. At the end of the 19th and beginning of the 20th century, often used to replace ivory and bone.
Although it's not the "real" thing and I have no clue how old it is. I do think it's lovely and my husband will use it to make a victorian/edwardian style walking cane for me. Or maybe it will end up as the handle of a parasol or umbrella.
