I have seen forums before where very knowledgable collectors will withhold certain important facts regarding the authenticity determination for certain parts because they don't want to reveal that important determining factor to potential counterfeiters. This can be very frustrating for the honest ones of us who really want to know for honest reasons.  Most of these people will reveal information privately, though, which does help. As Butlers said, counterfeiters can read through many of our posts here and know exactly what we look at to determine faked parts. Their skills evidently improve with time and experience!

Many of us have also made repairs to our Krags to try to restore them, in a legit fashion, to a more functional or historically correct condition. When we do that, we try to never allow it to be advertised, sold or misrepresented as "authentic" or "original" but repaired. I have done that myself, with the help of many here,  and it makes the collecting of Krags all the more fun.
