Would these dies be cut out by hand? Engraved? I'm sure I've read that before but these things look incredible.
.If they were it must have been incredibly difficult to do.
Thanks for sharing this photo collection of your friends dies
If they are all made by one firm maybe you can work out the maker of some hitherto unknown badges i.e. detemine the maker of just one of the dies from known info on badges and you will i.d. the rest - just a thought.
