Gun Digest lists a "matted rib grade" and "trap grade". The Western Field rebadge has a matted solid rib, schnabeled forend, and simple checkered diamonds on the forend, simple "three-point" checkered area on the grip. Letters "XC" follow the serial on one of mine; can't find the other one with the case color fresh; think it's in a box somewhere. Got a feeling from what Jim says that the schnabel and the checkering may only be found on the Western Field. Nice gun for knocking squirrel off tree limbs; nothing like tree limb for blocking shot. Not a trap gun but I did shoot an 18 at 16 yrd trap with my Dad's 20 ga. That's about as good as I'm doing with 12 gauge most of the time.
