I ran into a typical looking red SS Arm band with black piping at a estate sale. Upon closer inspection it looked period correct material and craftsmanship wise, but lacking any sort of RZM tag or stamp on the inside. So it is either a knockoff or is it possible tag was removed or it did not come with one in the first place? I did a search here but no luck. Seems unlikely a real one would lack a proper ID tag? Need short education here. Cheers, Jonny
