Hello,
What is the 3.7" HE/AT rocket warhead with electric base fuze No.931 from 50s ?
 
Maybe I am wrong, but do you mean the 94 mm (3.7-inch) LAW 80, introduced in 1987 instead of the 50s?

I have no info about the No. 931 fuze.
 
I think that's a typo and it's either 3" or 2.7". As far as I'm aware, the 3"RP didn't have a HEAT warhead. The 2.7" which is a 68mm SNEB, did. We, the UK, manufactured 68mm SNEB under licence and I suspect the 931 fuze was for our version of the HEAT rocket.

It transpires there was a hollow charge HE warhead for the 3" RP - Head HE, 12 lb, No. 1, Mk. 1. The fuze used was the No. 931.

Very briefly, there is a thermal initiator, the gases from which force a soft iron slug through an induction coil. The generated electrical charge is stored in a capacitor. There is a contact switch on the warhead, no further details. On impact the switch is closed and the circuit completed with the capacitor discharging through the detonator.

The 3-inch aircraft rocket mentioned in Air Publication 2802A from 1951 is the: Shell H.E. 60 lb., G.P. (hollow charge), rocket, aircraft, 3 in, No.1, Mk 1.
The fuze is the nose fuze No. 893 Mk 1.

In the Air Publication 2802A from 1971 is mentioned in the index also a Head, HEAT (hollow charge), Type 23. But deleted. So no info available.

Found some information about the type 23 warhead. It is one of the warheads belonging to the 68 mm FFAR SNEB F1 Rocket.
But still not a HEAT rocket with a No. 391 base fuze.
