Im liquidating another estate and have a bag of goodies. 1903A3 sight protector, 1873 Springfield Trapdoor tool, what looks to be pre64 Winchester swivel and studs and several what is its? Im thinking the mounts below the 1873 tool maybe claw mounts to a 1903A4.. this little graduated slide has Merit stamped on it, no clue on it and these dovetailed barrels, no clue. Few boxes of antique ammo are also cool
