A nice old copper black powder horn made by G & JW Hawksley of Sheffield, England in the mid 19th Century.
Measures 8" long and 3 1/2" across at the widest point. Made of copper with an embossed shell design on both sides. The top band, pourer and spring assembly are brass and the spout is marked with the maker's name and the amounts of powder to be used from 2 1/4 to 3 drams.
In nice condition with shallow dents here and there. It does not appear to have ever been cleaned or polished as there is lots of age-old patina overall. The spring mechanism still functions. There is no evidence that there were ever any rings or other attachments for a carrying strap.
