If what you are showing is that it was the same stamp that made the sigrunes inside a circle as seen on the Vz. 24, I’m in agreement. It looks to be the same stamp from what I am seeing in the image. As for top grip pictured that is labeled as a WKC blanko - that presented a little bit of a problem. As the only description I was able to find is as follows:

“Forum,
I pulled the last bayonet for the day. This SS Bayonet is very interesting and rare. It was originally mated with a Steyer bnz Single Rune 43.
The bayonet is as follows:
1. WKC Blade.
2. No WAs
3. SS Accountability #742 on the Ricasso.
4. Blanko Scabbard with #742
5. Excellent SS Property Stamp.
6. Single Rune on the Crossguard
7. 742 Numbered Grips
8. Wooden Grips
9. Grip SS Property Stamped
10. Grip dated 1943.
My opinion is that this bayonet could have been assembled and issued with the 1943 Steyer BNZ Single Rune Rifle.
Note: The grips seem oversize for the tang area. Grip sticks above Pommel & crossguard.”


But with this grip I see a 1940 date and no numbers. So what bayonet did it come from? Because it can't be the 1943 that was described at some length.
