It has become apparent, recently, that there are some holes in the H&R SPORTSMAN history and development both in the Double Action 999 and the Single Action 199. More research is warranted to fill in those holes. IF you own any H&R SPORTSMAN and would like to contribute to the research, I would appreciate the following information (pics would be a great asset):
1. Serial Number (partials are welcome, but entire numbers will help more)?
2. Firing pin on hammer or mounted in frame?
3. Safety rim on cylinder? PATENT APPLIED FOR; one patent number; two patent numbers?
4. Cylinder release: 1" long lever on right side -or- small push button on left side of frame right in front of cylinder.
5. Location of Manufacturer's address - on top of barrel -or- on right side?
6. DA or SA?
7. Adjustable or fixed front sight? If fixed - soldered in slot or pinned in slot?

Thanks in advance. I'll provide era of manufacture and Model and Variation determination for your SPORTSMAN.
