This approximately what Koenigs old house looked like when us kids decided to have a look in 1957.  We didn't know if anyone was home we were trying to investigate like "Spin and Marty" on "the Wonderful world of Disney".  As you can see John Koenig was already deceased in 1952, so the only person still living there was "John Vogler", John Koenig stepson.  He answered to people if you called him Johnny so we all just assumed it was John Koenig.
