Let me start by claiming to be an absolute novice, and congratulate you on your inheritance. Am wondering if the cheekpiece inlay could be aluminum? The reason I ask is that the butt stock layout of this gun looks very similar to a M. M. Benson rifle on page 121 of the "Gunsmiths of West Virginia". As I understand it the Benson family used aluminum for their inlays, a rather unique practice to their family. I believe they began in Preston County, but M. M moved to Fairmont at some point in his life. Anyway, the layout of the cheekpiece, the comb lines, the butt plate, trigger guard, and triggers look similar to my eye to the one pictured. I also note the triggerguard is held in by screws front and back, similar again to a M. M. Benson on page 120 of the same book.
