Mark Beasland usually has a few Huskys in his inventory.

Modern hammerguns . . . Bernardellis are also a good choice.
Hammer Elsies . . . although they came with 2 3/4" chambers (at least in 12ga--did they make any hammer 16's or 20's?), most of those guns predate the advent of the "modern" 2 3/4" shell, the first of which was John Olin's Super-X. That load increased the maximum service pressure by about 1,000 psi. I'd guess there are plenty of old Elsies out there that have been fed modern 2 3/4" shells with no harm done. But if I owned one, I'd reload to lower pressure levels, and I'd keep both the velocity and the payload down (maybe nothing over 1 1/8 oz) to reduce recoil. Might not make any difference, but I'd guess it might give old Elsie a better chance of long-term survival without either shooting loose or fracturing the wood.
