Larry,

They do exist on SA/NSKK daggers of the same period and are a bit easier to find because of larger production numbers.

I have never figured out the reason for the tapered nut. It seems to solve a non existent problem. It did not IMO facilitate assembly nor did it help "centering" any more than the regular system. I see no cost reduction or "ease of manufacturing" gains in the system. The fact that only a few daggers are found with this suggests that the experiment was limited.

That last photo was sent to me years ago by a fellow from Australia for my opinion. The trademark seems to be part of transitional Eickhorn trademark placed much higher than normal on the blade along with nothing else. He said he picked it up "from a mate". The only other picture I have is below. The fellow did not reply after a couple of emails. To my analysis, all the grip parts are genuine RZM. The blade, who knows ? Never saw the scabbard.
