grimlin13 I'm certainly in agreement that you see a lot of edged weapons that have been embellished with faustriemen/troddels/portepees. You really have to look at the wear patterns and aging, discoloration, etc to get a feel for the age. Even then it can be a SWAG. As far as the type of tie I'm not sure as far as bayonets. I know there are different styles of ties for various swords and daggers depending on the branch of service or organization. Like you, I seem to remember reading something about Police or Fire faustriemen/troddels/portepees attachment as well but struggling to remember any details.
Welcome of course KKW22cal. Knew that I had it; just had to find it. 2020 unless it kills me and I'm buried with the manuscript. I have tremendous respect for Bruce and Mike for what they accomplished in three volumes, four books. It's a lot of work and you don't want to disappoint people ....
