john, i wish you could have attended a seminar at the '05 eastern. unfortunately,my "name" memory is terrible,the rest of my memory ain't real good but, there were two rifle builders there, and they had made an exact copy of the air gun l& c carried, all hand made.found after disassembly of a airgun loaned to them to copy the loaner was indeed the same air gun carried across the U.S.by L&C three things on the loaner pointed to this fact, 1. was the mainspring had been replaced w/ one made from a file, 2. the second of 3 "clicks" on the hammer was broken and 3. the stock had been repaired and replaced w/ american walnut,while original stock was european walnut All were verified in the journals found,hand written by l&c...I wish they had done another seminar that week,cause i'd have been there again..lotta info! and one of the builders recreated the blackpowder rifle that was carried too...boy i wish i could remember it all... i'll check and see if i have the booklet w/ their names in it... i'll never forget it,they actually let us shoot the air rifle and gave us a ball from it...what a great story!! wish i could be of more help,i'm pretty sure that the owner of the original air gun has alot to do w/ bemus(?) air guns.. older gent,has had the gun for 30 years and didn't know it was the original...
