I have a very nice M43 Spanish Mauser Civil Guard edition. Sword, scabbard and fasces crest on receiver plus same emblem on right side of buttstock. Wood looks very good. Couple little minor blems, nothing serious. Bluing looks good, may have some minor surface rust. A thin coat of oil really brings it out. Bore is strong but dark. Any idea what this fine old rifle might be worth? Thanks in advance.
