It seems to be my week for squeezing WW for its collective knowledge.
I've a very vague memory that one of the little oddities of WW2 was strips or coils of silver metal, maybe from trying to baffle enemy wireless? Picked up from the ground by small scavenging boys, anyway, or found serendipitously in some way. I want to hang them on my wartime Christmas tree.
Does anyone have any idea of what I'm talking about?
