The basic problem with cracks in the LC Smith stocks id the design of the action. The rotary bolt, the top lever spindle, the safety and the cocking cams all require removal of a lot of wood. Nearly always, the width of the vertical channel for the spindle is larger than necessary, which leaves even less wood. Based on my observations, hammerguns are much less likely to have cracks because they need less wood removed, and have shorter tangs. The decreasing availability of quality stock wood over the years of production probably played a part also. Gluing cracks and glass betting the action and locks will cure almost all of the problems.
