Each of these badges, likely from the 1920s, consists of a celluloid front held in a quite heavy silvered brass metal frame with vertical pin and lock on the reverse along with back stamp of maker W&H which includes a 1921 patent date. Each badge has a serial number with badges in black designated “A” class and those in red designated “B” class. All have many light surface scratches but they are truly on the surface and really just show somewhat in reflected light. Early badges and very well made. Paul Muchinsky Collection.
