Despite photos reflecting blue light, I believe it is true that one can witness original blueing which is blue in color. I have seen it on pre-war european guns, and on some early american revolvers. Is there a proprietary secret? Would some of our overseas contributors like to chime in? Certainly, this site is a place where the service-minded contributions of knowledgeable people has trancended political barriers and created a brotherhood supportive of worldwide hunting, collecting, and conservation causes and issues. I don't know when I have been exposed to more knowledge which just would not have come about without the blogging of Ellenber, Kaduae, and so many others. Particularly can one be appreciative when so many records were destroyed in the two world wars. The Mannlicher Collectors Assoc. is always trying to fill in the voids on serialization, and all sorts of issues in archiving information about their favorite rifles. Soon, such knowledge may pass with the deaths of those who were around and KNEW. Ditto for this blueing thread. I surely await the contributions of those who may know of proprietory or secretive methods. My hat is off to you, and I for one am deeply appreciative!! Steve
