Have seen em at the Ohio longrifle show in Marrietta,Oh,and in some books.I have built 2,one in walnut,other in cherry.Walnut one uses pins,cherry has a single key and tang screw to take down.Pics of walnut rifle are on gunsinternational for sale---mountainman-is my name.A neat way to build.The walnut rifle was made from same board as forestock,just wasnt enough wood to get another fullstock,so we got a half and a forestock,and a nice long barrel,found a relic butt on ebay,complete with furniture,and built it off the relic layout.Thanks,Dave
