Pete, Raimey:
I can answer a few of your questions, i.e: the H&H order sheet for double rifle #7480 is January 3, 1883; I am an upland bird hunter primarily, plus a long time member of the Calif. SxS Society; have a small collection of English sxs's; have yet to shoot this rifle; have nitro for black powder shells made by Superior for it; have the camera and program to take a picture of the "order sheet"; have read and reread J.H.Walsh's 1882 2 vol. classic "The Sportsmans Gun and Rifle" to try and solve these questions about the order sheet and the meaning of NA; and have queried George Hoyem. I'll try to take a picture! Thanks all. Herb
