Dopp. Z. 10cm Vz. 21n

[Bever]

Hello ,

I wanted to see what the thread type was for the Czech 10cm Vz. 21n Doppelzünder. But as you can see , the thread on the one in the pictures is pretty much completely flattened.

The 15cm Vz. 25 Doppelzünder seems to be M56 x 2,5 , but I’m not completely sure if this one has the same thread.

So if any of you have more data on this , would be much appreciated if you’d share.

many thanks !

M57x2,5 is the size

Btw. it's one of the largest and heaviest artillery fuzes I think.
