That is what I thought. This thing is somewhat of an anomaly. I will try to snap some photos this week end. The bayonet and nose piece have been plated but most of it is gone leaving sort of a patina not blue not rust. The receiver has no plating with the same patina, The butt plate has a light coating as does the bolt release and the rear portion of the trigger guard and the barrel under the handguard. The numbers all match including the furniture.
I do not want to reblue and am comfortable with what I am calling patina. Photos forthcoming.
