Looking for information about this fuze

[Fjordhouse]

I am looking for information about this bombfuze. First I thought it a German nr 40 but that’s not possible it say 4 U so I hope that someone has information about this fuze

I can also be another country I think it’s German but I can be wrong

Regards
Ben

Apart from the setting knob it is very similar to the AZ 24 used in the SB2500.

It seems to be an early 34b but still no documentation about this fuze

The German Marine Dienstvorschrift Nr. 452 (M.Dv. Nr. 452) about Luftminen (1944) mention the following about the Zusatzzünder Z 34 B: The working and description about the fuze is written in the German Luftwaffe Dienstvorschrift g 152/32 (L.Dv. g 152/32) (1943).

I do not have this German Air Force manual, maybe someone else?

I came across photos on Facebook (I don't know the author).

We probably know the type (34) A...

On the left is the type (34) B, on the right is the type (4u).
---------
The type (34) B has, among other things, a special feature, which is a hydrostatic target sensor... the purpose of the igniter is primarily to destroy a mine if it falls outside the water or into shallow water.
That is, t



o eliminate the risk of mine misalignment and to understand the design.



Foto right the type (4 u) has a mechanical transport safety (I am not sure if this is a unique solution or has been used elsewhere) and as for the other stages of unlocking, it is using a clockwork. The target sensor itself is purely impact. (duplicate)It contains 2 independent impact systems in a 90-degree position and are similar to the type modification ... or ? 80A.

It looks like a (24), which was found in the first magnetic mine successfully recovered at Shoeburyness, Nov 1939 ( succeeded by the VzZ(34)A & then the . The fuze can be seen at the foot of the mine in the photo on page 55 of The Blitz Then & Now vol 1. It was then used in a modified form as the top part of the (24)A, used in the SB2500 bomb.
