I stand corrected on when the daggers came out. Of course, the daggers came out a couple of years prior to 1935. I should have said that instead of what I did say. It's odd that the bayonets carried RZM markings a good while prior to their appearing on daggers. I have seen at least one photo of an SS man wearing a short dress bayonet with the "NCO" portepee with runes on the stem. Wittmann seems to think those portepees were for the SD. Perhaps the RZM bayonets have some connection there? The RZM bayonet I have came with such a portepee, also dated 1935.
