I'm looking at a Greek "mix-master" that appears to have the original barrel and N.S. bolt body, all in very decent condition. The parkerizing appears to be the standard, dark-gray GI type I would expect from a late production rifle (as opposed to the "inky" black finish often encountered on these Greek returns). The lone exception is the receiver, which is a distinct bronze color. The receiver is nice and clean, with sharp, crisp markings and no evidence of being sand blasted. Can anyone shed any light on the odd receiver finish, or the likelihood of the barrel being original to the receiver? Thanks in advance for your help.
