Shaw, i just bought three highly figured english walnut blanks that fit the shape of my current BSR. They are about 30-35 years old, pretty dry and stable now. Yes, they are expensive. For a once-in-a-lifetime custom rifle…why not. These come from a now retired custom gun maker out West. He does have more blanks, most of which are cut to fit modern unmentionables stocks, which are straighter than bp. Finding one or two that fit the bend or drop of a bp rifle stock is tough, but doable. I sent him a tracing of my gun and he sent me pictures of how it fit each blank. I will ask him about how to let people know about what he has, then I will get back to you. As for the BSR flintlock, I found two that seemed most appropriate: The late Ketland, which is probably best made by Jim Kibler, and the distinctive Manton-style “waterproof pan,” which has great eye appeal to me. That is the style I chose, and went with Davis. Rice makes the same Manton style, and Dave Person has written in detail about his experience with it. My sense is that until Kibler makes a Manton-style lock, we have a choice of two very similar ones that each require substantial work. The roller frizzen is amazingly fast, and also a liability in the thick woods, if you stalk or move around at all. That frizzen is so fast it is almost like a hair trigger, set to pop open at the lightest touch.
Below is the one English walnut stock blank I bought that I like the most for the next BSR, which will be percussion.
