RAF code's air dropped mines

Hello Antoon,

The codes are standing for the differnet firing-assemblies.
A: magnetic, single-pole induction
B: magnetic, requires two actuations of opposite polarity
C: magnetic, requires random looks
D: acoustic, various sensitivities available
G: combined magnetic-acoustic
J: combined pressure-magnetic
K: acoustic, various sensitivities available (=D)

I have some sketches where the ASY codes are on the mines: B204 was a Mk VIII, K1010 was a Mk VI,...
But as you know, all these mines could be fitted with different firing assemblies, so I wouldn't relate too much on this.

In the M.Dv. Nr. 454 (Marine Dienstvorschrift 454) are some tables wich explain the different firing assemblies and the german names for these assemblies.

Greetz,

Stef
