Original vintage vitreous enamel badges were almost always produced as hinged badges with a metal loop on top for attaching the badge to the leather keyfob .
The badge is then connected to the leather keyfob by means of a hinged leather strap.
Vitreous enamel was used by ancient Egyptian civilisations and there are examples from that time which are still as vibrant and fresh as the day they were made.
Manufacturers have mostly now gone over to producing modern resin based enamel badges .
From the 1950s to the early 1970s – vitreous enamel was all that was available.
