The items in question were the B1 soviet depth charge with and without pistons. Those fitted with pistons were destroyed first, whilst the remainder go for demolition in early 2020. I have the technical data if anyone requires it.

The only real issue I see without the pistol installed is explosive instability. This was supposedly discontinued after or around 1950s’.

I know the fuse was tetryl but idk main charge.

BB1, Total weight, 363.7 lbs (165kg)
Explosive weight 300 lbs (135kg) TN

I have some technical information on the USSR B1 Depth charge, which may be of some use to you. I would prefer to send it direct to you rather than an open format. Please provide an email address, if you still require the information.

Regards

Adam
