The Art of Wingshooting William Bruce Leffingwell, 1895
http://books.google.com/books?id=e34EmE3tkfkC I was permitted to examine many of the fine guns used by Miss Oakley in exhibition shooting, and noticed among them one Charles Lancaster ejector, one Charles Lancaster nonejector, a Cashmore hammerless, a magnificent Smith ejector with a gold figure of herself inlaid, a Parker hammerless, a Scott Monte Carlo, a Scott ejector of highest quality, and an exquisite little Francotte ejector with Whitworth barrels. The value of the guns mentioned is $2,500.
The rifles shown were Lancaster oval-bore .360 double-barrel, Holland hammerless .32-caliber double-barrel, a magnificent Marlin repeater, and a couple of handsome Winchesters. She also showed me two single-barreled pistols made by the celebrated maker, Gastinne Renette of Paris. These pistols have 14-inch barrels, and are made expressly for pigeon shooting. With them Miss Oakley has scored nine out of ten pigeons from two traps, using one-half ounce of shot.
She shoots binocularly. Her shot-guns weigh about six pounds each, the right barrels being bored modified, and the left full choke. Her load for targets is 2 3/4 drams of nitro powder and one ounce of shot. For live pigeons she uses three drams of powder, but the shot charge is unchanged; an ounce of shot is used on all occasions and for all kinds of game.
Frank Butler "conducted" a number of Annie's gift guns for immediate resale, and it is possible that a Lewis was among the bunch.
