I'm selling a couple of German bows...They'll be in classifieds of course. One is an H.R. Phretzner, the other, i'd like to get some info. on to price it. It's by Keith Beardon, 1942, octagon pernambuco stick, silver mounted, with an abalone inlay on the German frog. For a German bow, the work is extra fine. Any information would really help me price this bow.
