Roger, do you have some examples of bogus Nimschke engraved guns or signatures you could share with us ? Wilson has quite a few examples in his book. Are there guns there that are suspect ?
Daryl,
I have several images of examples of fake LDNs. I also see them at gun shows frequently. I won't display the images on a public forum however because I would be "outing" the owners who might take issue. I'm sure that some of those selling fake LDNs know it or may have been party to the counterfieting but many others really believe they have a gem.
It would be fair to ask how I know the difference. I can only say that I have made a study of the subject because it is something I am frequently asked about. There is also a book that features microscopic photograqphy that addresses the subject. It is entitled
Gun Engraving as Decorative Art by the late Dr. Fredric A. Harris.
Regards,
Roger
