There are other expensive options, depending on the stock maker. My H&H No. 2 made in 1906 was acquired from Jim Bell, who brought it back from India, where he had been in the Peace Corps. He had a new butt stock made for left hand shooting by Al Biesen. Al of course is legendary and while still alive, I understand that his son is doing the work now. It might be worth getting an estimate.

I also got Jim's dies and a bunch of his B.E.L.L. brass.
