George Anderson provided both the artillery, the 2 drums and a matching Baden pickelhaube. It wasn't till I actually held mine that I realise they weren't made of metal. I guess they were replaced by metal more familiar sometime during later during the later part of first world war. They are so fragile and can't believe any survived!!! This is by far the finest source on the subject!
