Double Bond was the stuff's name. I made a few gizzets out of the stuff for the lads when I was at 7SU in the late 1980's. During the Mid 1990's I did a load of them while on 144SU. The Supplier there must of ordered most of the MOD's stock as I had 400 packets of the stuff. Used it all.
I still have my ‘Pengy Piece’ from my FI det, we all made them for each other on our crew although some were better than others and the poor ones were usually left behind… mine was made by my captain and is something of a work of art in my opinion, so much so that it is still sitting on the windowsill behind my desk, 30 years later. I have had to be somewhat vague in explaining what the various tableau refer to…(various penguins enact scenes from your tour!)
The one I made for him was equally artistic I thought but he felt a little aggrieved at some of it so didn’t take it home!
As I understand the stuff was really expensive so each one cost hundreds of pounds.
