If you can live with/like 6x4.5 format, the Kodak Duo-Six 20 is a very nice little camera, the series 2 being the most easily available. Made in Stuttgart in the late thirties by Dr. Nagelwerke/Kodak AG, they have either an f3.5 Kodak Anastigmat, Zeiss Tessar, or Schneider Xenon lens with focal length of 70 or 75mm, in a Compur or Compur Rapid shutter. They are strong, light, and elegant, a bit like a Retina on steroids!
