I wonder how old this wedge could be...
without any doubt a generic one and most likely made by an apprentice ?
three crowns ? could not trace a maker with this markings - very crude tang with a scratch marking but left unfinished
scales are dyed red going towards purple - looks like a hurry job on the pinning too
the razor was found in an old barbershop in Giethoorn (The Netherlands)
thanks
