I've been given a p.1856 Enfield bayonet by a friend. It had been in his family's cottage here in Manitoba for decades, and is in relic condition. The only marking I've been able to find is a 'C' over '2' on the top of the pommel. It has a screw retaining the spring, which I've read dates it from 1858-on......I'd appreciate any info. on the C over 2 marking, and who would have used this bayonet when? Thanks for any ideas or leads offered. - Rob
