These historically correct replica badges were reproduced from originals that can be found in museums and private collections. They are nickel plated with a sturdy pin fastener on the back.
The historical information provided with the badges is to provide interesting facts from history. The people mentioned in the descriptions may or may not have worn a badge similiar to the one depicted. The only connection is that they served in the capacity as indicated by the badge.
I hope you enjoy reading the history notes as much as I enjoyed researching them.
