Well, I feel better knowing so many other have dealt with the same problem. Thanks for sharing!
As far as the wood choice goes, I purchased this "in the white" from the estate of my old friend Fred Schelter. He purchased the Getz barrel and had Fred Miller (I believe) inlet it and pre-shape the stock in 2000-2001. Whether it was his wood or Miller's, I don't know. He had two Armstrong stocks done this way at the same time, one was a .50 cal (sold) and this .40 cal, rifle. Fred S. did the carving and inlay of the patchbox, butt, toe plate, nose cap, and trigger and guard. He had made the forend escutcheons for the barrel keys, but didn't inlay them.
Both stocks were inletted and drilled for a large Dlx. Siler Flintlock, but only one lock existed and it was curiously interchangeable. So I had to buy a second lock to complete this one. I fashioned a new trigger for a lighter pull and made a patchbox release, side plate and sights. Then I did the engraving and finish work.
...so, now you know...the rest of the story!
