Mook Machine solid & skeleton (Glen Fewless); Treebone cast steel; McFarland solid (shotgun shape) & skeleton (rifle shape).
The cast one doesn't look so good but I guess I saw too many second rate castings when I built muzzleloaders. According to my notes the cast one cost $30 while the others are $90-$150.
