This makes sense. Thereís a guy selling a bunch of Leica stuff near me that doesnít know much about cameras. Heís mixing and matching pictures for the stuff he is selling. Heís also selling a 50mm DR Summicron. I remember reading something about goggles for a 21mm sometime back and assumed thatís what he was selling. I assumed wrong. As pointed out, the goggles are for a DR Summicron and the finder is for the 21mm.
Thanks for clearing this up.
