Hi Adi , yes i would say it was more than possible that some were issued to the germans unmarked ! Pre war there were as many as 1.3 million vz23 and vz24 models exported all over the world . When the German Army siezed Czechoslovakia and of course the arms factories the vz24 and vz33 models were issued to german troops. Interestingly german ballistics experts found that when these bayonets were fixed to weapons firing accuracy was compromised and so had the muzzle rings removed !
I believe I have also gotten my hands on one of these bayonets. I have found many serial numbers on it and I was wondering if anyone could help me identify what all of them are for and possibly the value of this piece.
The second picture has what looks like a circle with a Z inside it and a M inside a small square.
The sixth picture has a very small M with a line under it.
The last picture has what looks like what is left of an E in front of the R 9547.
