Yes, you guys DO have a lot of experience with them, and that is entirely
valid but that doesn't negate the fact that the statement was summarily
dismissive, and even more so, possibly wrong.

Experience has nothing to do with it.  It's called design.  The mechanism
was designed to operate in a certain range, and I haven't reviewed the
design to see what it was designed for.  There is nothing wrong with
adjusting it and just using it, that's entirely valid...but I wouldn't
manufacture something from just that alone, it would be foolish.  At least
according to the 75 year book, my concern was entirely valid, at least
Rollei believed so, or at least someone said Rollei believed so!

It means I understand a LOT about mechanical systems, and how they are
designed and work.

Prochnow can make mistakes.

I love it.  (this is not aimed at you, BTW)...  When Prochnow (or anyone)
says what someone believes, he is right on the money, and THE authority,
when he says something that doesn't agree, well, then he is mistaken.  We
all do it ;-)

It will and does for the ones that YOU know of...

I think what was said was out of line, and that's must my opinion...but
interestingly enough, what was said to be "bullshit" has now been shown to
be entirely true.  The initial statement that was claimed "bullshit" was
that someone saw what was said in the 75th book...which was stated as "saw
somewhere", and now we have identified the source...so the source is real,
the statement is real...now what the truth of the statement is, I can't say
for sure...but it does make sense, didn't say it's right or not, but it does
make sense, at least to me.

Horse <= dead...I hope ;-)
