The Fed-X gentleman just brought a package to containing my "new" Alex Henry double rifle. I am looking for information on its date of mfg. caliber etc. and would appreciate any help provided. It is my first double rifle and even in its current shape, gives me the same tingling as do my double shotguns. Its serial number is 2400, and its a 450 cal. damascus, underlever hammergun with 1 non-folding sight. The proof marks are somewhat confusion as one is a London voluntary special proof with extra heavy load, (crown over LP) and then also a Birmingham final black powder proof (crown over crossed swords with B/C/P). It needs a replacement stock and forend as well as re-browning and some minor mechanical work to return it to its former beauty. I will try to post photos in a couple of days.
Aloha,
Kevin
