GC Mine (LMB III) with two fuze pockets

[Antoon]

Best wishes for 2025.

In the German navy manual M.Dv. Nr. 245, LM [LMA III, LMB III, LMB (P), LMB (S)] from 1944 is mentioned the LMB III with two fuze pockets.
I can only find these GC mine with one fuze pocket. Should these been the LMB I and/or LMB II.

Has someone a picture of this mine LMB III with two fuze pockets?

Greetings - Antoon

What date is the manual? Might be a later variant.
