English Solid 9 KT Gold Thread Winder - Circa 1860 - has hand engraved detail, different on each side. Made before English goldsmiths had to hallmark, and pay duty on, small items of gold and silver. Measures 3/4" in diameter. Weighs 1.8 grams. It was once in the collection of Diane Pelham Burn and a very similar one is shown in the middle plate on p. 18 of her excellent book Thread Winders, A Collector's Guide.
