Thanks, Stagman, for your thoughtful response to my inquiry about the age, and markings on my old Marble's knife. I have not been able to discern what you are saying about the A being worn off, as it seems to be all there. About the mark looping to the left, I don't understand. Since I had the knife during WW2 , I think it is safe to say that it was made in the 1915- 1935 era. I still don't know why the washers, and spacers show as they do, but I still love this old knife, and remember the English Commando dagger, that I traded for it, the boy that I traded with, to get the marble's knife, and am going to enjoy it just as it is regardless of it's history.
It's Mind Over Matter, If You Don't Mind, It Don't Matter
