Hi Aldo35, I think that the acceptance and proof stamps were applied prior to final finish and buffing/bluing? So, not sure? You'd have to have in hand to really tell? At this point with the pictures available, I'm guessing it's for real... But, again, wouldn't bet the house on it? ... I recommended to Troy to pursue it, as if real, it is real nice!!!.. Best, til....lat'r....GT...
Follow up, I private messaged Troy and advised he inspect the unit further in order to determine originality of the finish? My gut feeling is, by the pictures shown, still, that it is original, but better and more clear photos might (probably will!) prove me wrong.. It will be interesting to find out... I'm at the end of my ability to add anything further, some of you Mauser guys need to chime in, maybe some comp pics of the proofs! Best to all, til.....lat'r....GT
