Eric,
It is ABSOLUTELY necessarily so! Ya gotta have the referenced
knob in the kit or originally on the camera like the 2.8C. There is
NFW that 35mm film can be used without it!
BTW, my cousin Hy designed and marketed a conversion kit to
use Bantam 828 film in the Rollei. Called it the Adapto-Back. Do
any of you recall seeing that kit?

Jerry, you missed the point. Some Rollei models came from the factory
with the indexing counter knob as standard equipment. The Rolleikin kits
for these cameras did not include the counter knob because the cameras
did not have to be modified.
For models that did not come with the indexing knob you are absolutely
right that the Rollikin is useless without it. Kits with the indexing
knob are substantially more expensive than those without because they
are much rarer. Such a kit should also include the mounting screws
because they are longer than the originals.
