I have a 1973 50 cal. custom made by gunsmith Don Anspaugh.. The rifle is inline and has a side break with large musket cap. I like to hunt with a muzzleloader and have hunted with this rifle but it is to nice to take into the woods. Trying to find out a value of the rifle. . . {mod. edit: attempts to sell require using the Trading Post forum; that takes 25 posts and two weeks}
