Subject: [rollei_list] Henry Schering
I have never had Henry overhaul any of my
cameras. I have only heard the highest praise
for his work; the only criticism is that he is
back-logged, itself an endorsement of the quality of his
repairs.
However, Henry tends to develop theories about
Zeiss Ikon cameras and then to preach these so
that they do develop some traction. Several
times, over on the Zeiss Ikon Collectors' Group,
we have tried to run down such rumors and all, in
the end, trace back to Henry. I suspect that
that is what has happened here. Henry has
developed a theory unique to himself that there
is some inherent design flaw in the film-spacing
on Super Ikonta cameras. He has said this so
many times that others have come to believe it
and, now, when you hear, "I have heard it
elsewhere", it almost certainly can be traced back to Henry.
We have corporate knowledge of a hundred or more
of these cameras in various formats, and the only
ones which consistently seem to have suspicions
of fram-spacing woes are those which have come to
Henry's attention. Otherwise, the cameras seem
to function flawlessly in that regard unless they
are in need of a CLA. A properly serviced Super
Ikonta should not have any spacing problems.
I had Ken Ruth CLA one of my Super Ikontas and
John Van Stelten the other. Both came back without a
problem.

There must somewhere be repair manuals for these
cameras which show the mechanism. It would be useful to know
exactly how the camera meters the film. That would certainly
answer any questions about uneven spacing and what could
cause it.
I am skeptical about film thickness being the culprit.
Again, I suspect there are records of standards for both
film support and paper backing thickness. Roll film has been
around for a very long time, well over a century, so I
suspect there were some standards developed pretty early.
The Rolleiflex automatic and Rolleicord measure the
diameter of the take up roll but many other cameras have
simpler mechanisms. For intstance, the various roll film
adaptors for sheet film cameras have cogged wheels to fix
spacing. As long as these are working properly they produce
reasonably even spacing regardless of the film.
I am still puzzled why the original Super Ikonta B
allows only 11 frames per roll. Perhaps it was done to
compensate for some irregularity in either film or camera.
The BX version allows 12 frames. I don't think this was
simply a matter of its beeing the "deluxe" model. Perhaps
there was competition from other 120/B2 camereas which did
yield 12 frames.
