The shutter worked for one speed only and it is broken after a repair
attempt , it no longer works, however I could take this photo before the
attempt:

These are samples about popular 6,5 x 9 cm (and other plate sizes) cameras
when F&H decided to manufacture the Rollei Plate Adapter in 1932.-

Color film was not mentioned in the F&H documents about the
first Rolleikin, On December 6, 1932 the minutes of a meeting attended by
Paul Franke and Reinhold Heidecke mentioned the Rolleikin for the first
time: "An accessory was presented that is designed for the use of 35mm film
. The design was approved . It is to be presented again when finished". The
Rollei Report I says the Rolleikin became one of the mos important
accessories; "...The continual improvement of photographic emulsions with
finer grain enabled the Leica to sweep the market. . 35mm film was cheaper
than roll film. , above all when users were loading bulk film. Suitable
cartridges were supplied by Leitz, Contax and now F&H..."; this was the
original reason to manufacture the Rolleikin , to allow the Rolleiflex
users to load the cheaper bulk 35mm film (Claus Prochnow, Rollei Report I,
page 12-263). The F&H 1936 catalog said about the Rolleikin" The 35mm
attachment combines the superior features of the 6x6 Rolleiflex and the
Rolleicord with the use of low priced 35mm film. Up to 36 exposures with a
size of 24x36mm can be taken on this material. This makes the 35mm
attachment particularly useful, for example, for news photography where a
large number of pjotos have to be taken in rapid succession without
changing film..." (Report I page 12-266); color film is not mentioned in
this 1936 F&H catalog. It was in 1939 when color film was mentioned for
the first time for the Rolleikin because the new color reversal films made
necessary a fourth Rolleikin version: Kodak required the film to be wound
back into its original cartridge for developing. "Now the exposed film
could be rewound and removed from the camera in daylight" (Report I, page
12-263).
It is clear the Rolleikin was built for economical reasons, it was later
useful for the new color films.
The glass plates and film sheets us have the advantages and special uses
you and others mentioned and they were the main reason the Rollei Plate
Adapter was built from 1932 up to 1981, however there also was an
economical reason originally, the 6,5x9cm cameras like some Voigtländer
models were popular in the 30s and F&H wanted to offer an option to their
customers in this format too.

One reason for the devising of both the plate back and the
35mm adapter was to allow the use of early color film. The
earliest was of the type using dyed particles or color stripes on
glass plates or even color separation using sequential frames for
each color. Somewhat later color films, such as Kodachrome, were
not available as roll film but were sold as 35mm film and sheet
film. There are other reasons. One of which may be the improved
flatness of glass plates and convenience of single frames when a
camera is adapted for scientific photography.
