Dirty Water thanks for your input. It is appreciated and the manner in which it was stated is very much appreciated.
Ron and Joe I have known both of you for many years now thanks to the RKS and I am never anything but truly amazed at your knowledge of Randall Made Knives. Ron the unmarked knives remain a mystery and although I agree with Scott and the fact that there are perhaps many former employees perfectly capable of making an exact copy of any Randall Knife I cannot rule out Bo Randall's patriotism and a feeling that if he had been asked to supply the CIA with a quality fighting knife in a sterile condition and to not divulge the fact that he had done it, that he would keep that secret for life. As bazarr as that may seem. After all there are several fine examples of Model 1's and 2's without a trademark around and in fine collections. Joe I hit all around the fact that it was a NASA knife without actually saying it for sure. Thanks for stepping up and calling it what it is. I didn't think about the training knives. If it's a tuff question we can depend on you and Ron to step up to the plate.
Scott the fact that you have never seen RMK etch or engrave on a knife as the Mod. 2 Ron shows is understandable since Randall had the engraving done outside the shop by a company in Orlando up until the 1960's. I don't remember the exact dates when Randall started engraving but I believe it was after the Astro knives were made for NASA.
In regards to the Astro posted here by Tunefink...well needless to say it's gonna bring a lot of money. How much? Any ideas? I may have to get in the race! It would look awfully good in my collection. To quote the British SCO (Senior Commanding Officer) in the movie, "The Great Escape", "it's good stuff, Hilts."
