39 will be the date not sure what the other markings mean
I would assume that the '8' would stand for August.
tnx all for replay, and so I figured it might be August 1939!...?
nice MG belt,you don't often see them as clean as that.
642 = Boehme und Co, Dr. Jng., Werk Minden, Werksleitung Lüdenscheid, Nordrhein-Westfalen, so I think B is for Boehme....
I could not find anywhere cod WaA642......?!
