Napoleonic era, 1796-1815. 2 5/8" length. Intricately pierced. The bottom threaded for a spherical cap, no longer with. Made with a bow lathe and bow drill at Norman Cross, Cambridgeshire England where thousands of Napoleon’s troops were housed after capture. They were allowed to produce a great variety of articles which were sold at the town market and prison gate. With over 5000 prisoners, production was substantial. Many prisoners became highly skilled and some acquired significant funds for their efforts, as the prices for their work was regulated as to not undersell English competition. Lovely example.
