3,7cm Kpf. Z.

[Bever]

Hi, In attachment a 3,7cm fuze , only marking is the WaA. Is this an active fuze or dummy fuze ? as the top is closed. And if any of you know, what type is this?

Any help is greatly appreciated. Thank you

Looks exactly like the Ersatzstück pictured in Mr Kochs book.

Is it a Ersatzstück though? It has fitting for a zdlg , not entschärft or anything. Just a WaA

The internal thread is for a Duplex detonator (Sprengkapsel). This is initiated by the impact of a needle.
There needs to be a hole in the bottom center.
I could imagine a 3,7 cm Kpf. Z. Zerl. P.v without the impact mechanism with only the SD feature for test purpouses, but without an X-ray or disassembly it is impossible to determine.

If you are not sure, if it is live or not, local EOD will be glad to assist you

It definitely is not live. Was just wondering as it is quite different from most entschärft , Ex. or Ersst. 3,7cm kpf z.
