WW2 Collector thank you for sharing your opinion based on your experience and knowledge. I also thought (but had no experience) that the all brass daggers are the most early ones.
Interestingly the heavily silvered leightweight fittings were used by more firms we commonly might think, I have or have had them eg. on my HARTKOPF, a PUMA and a PLÜMACHER.
