T-770 nose bomb fuze, anti-disturbance

[Mrfuze]

Hello to all fuze collectors!!!!!
Here I want to share some images from a very rare nose bomb fuze, which was (even with the T-number) issued in early Vietnam aera end of the 60's. This development was made to put a stop against the recovery of explosives in unexploded bombs by the Vietcong, since these explosives were used against the US again in improvised munitions.
A slight movement or close by vibration will close the very sensitive electrical contacts , thus activating the bomb filer.

Very pretty cut-away!
Any info on how it functions? Details on the switch?
I've never seen this one before.

To E-tech,
here are the close up images of the contact assembly.

hmm- not as close of a copy of the Type (50) fuze as I thought it would be.
Looks like it may have been "inspired" by the Type (50) fuze- but it seems the design was adapted to cheaper/faster manufacturing.
Actually, the weighted leaf-spring design looks closer to some old CIA built toys. They had built a few anti-disturbance devices with similar switches in the 1950s.

MrFuze: By "AD mine" do you mean the little black box that was supposed to be placed in a desk drawer (along w/13oz. of PE4)?
I've seen one of them before (in a really nice collection!)- strangely enough, they didn't use leaf-type contacts with weights, or even weighted springs. The AD mine I saw had a strange "dowsing rod" kind of arrangement.

To e-tech: here the image of the ADM and the contact assembly.
Have fun
