Very nice photographs. That 35mm TLR prototype was a project to keep
alive the Rolleiflex 4x4 spirit after an attempt to develop a
Rolleikin for this camera that had major problems because the 127 film
chamber room was not enough for the special 35 mm spool. The 4x4 had
no good sales and Reinhold Heidecke was very enthusiastic about the
camera, it explains why he resurrected the 4x4 during the '50s. The
35mm prototype was based on the pre-war 4x4 and it was developed from
1940 to 1941. One of the main problems for this prototype was the film
vertical run, the vertical format was the natural way to shoot the
camera and it required awkward positions for the horizontal format
like the 6x6 with the Rolleikin, but the Rolleikin was used for
specific situations only. The prototype did not have automatic shutter
tensioning with the film advance, the film counter stopped with the
exposure 36 and it was reset to zero by hand, the camera couldn't
compete against other 35mm cameras seriously without major changes.
The 9x9 prototypes were developed in 1931, 10 years before the 35mm
prototype, there is a slight error in the page about it.
Interesting Brazilian web site, they were Russian-Soviet cameras and
lenses importer for Brazil from 1967, they had a technical service
dedicated to review and to adjust the items before to sale them, they
evolved along the years and they manufacture special pieces and
special cameras and stereo cameras and microscopes and telescopes
requiring special and dedicated specs.
