A pal of mine has given me this pin to try to sort out for him. It's made of thin, flat metal, clearly hand crafted and has a large brooch pin crudely soldered to the back. It's 44mm wide, 1mm thick and made of the oddest looking metal. It's non-magnetic and has a brassy appearance but it's not tarnished like brass, more like a bronze/silver. It's not die struck, the edges show jewellers saw marks. Not my field and I'm completely stumped by this one.
