Paul Franke and Reinhold Heidecke founded the firm 
of Franke & Heidecke. The 1st camera produced was the 45mm X 107mm Heidoscop (Stereoscope Camera.) that used plate film.
( If you've never seen a Heidoscop or Rolleidoscop, click on the name. They're fascinating cameras.)
I do not yet have either a Heidoscop or Rolleidoscop in my collection. The images of these 2 cameras were kindly provided by Leica Shop-Vienna.
A second Heidoscope was produced but used 60mm X 130mm plate flm.
The Rolleidoscop was introduced for B11 or 117 roll film. In 1927 a smaller version was introduced to accept 127 film. All of the above cameras continued in production until the World War 11.
The first Rolleiflex. This is called the "Original Rolleiflex." Both f4.5 and f3.8 models were introduced.
