• Wehrmachtgerät. Diode; Feldstärkeanzeige. Von Blaupunkt und/oder Philips hergestellt? Von wem noch? WR1/P (Rudy) was manufactured by Philips. My sources say "Philips Deutschland". Blaupunkt model was WR1 (this is on the label) though here and there it was called WR1/T. We have both models at RKK Radio Museum in Moscow, Russia.
