Hmm I now cannot find the article where I read about 20% of Ricoh sales being the Pentax 17 but it probably meant to refer to the Photo division.
It's unclear to me where such a figure would have come from. Ricoh does not publish financial figures at this detail level. There is also no 'Photo division' in Ricoh; there's a Camera division that's usually listed under the 'Other' category in the business unit overview and it's not clear whether that unit (insofar as it's actually a unit; it's typically Japanese-vague) is the only within the 'Other' category or not. The 'Other' category accounts for something like 1.5% of Ricoh's revenue. Breakdown of revenue within this unit towards specific product lines is not given, as is customary for companies of this nature.
The only 20% reference I could find is
a post of yourself dated March 26 of this year. You didn't provide a reference back then either.
This is a typical case of "I think a spoke to a guy who read something about some bloke who heard a rumor that..." and before you know it, it's a 'fact'.
We don't know how many Pentax 17's were sold and we're likely never going to find out either.
The only people in a position to say something along the lines of the 20% remark would either be accountants or controllers intimately involved in Ricoh's financial administration or SBU managers; they're bound to secrecy and likely for the most part Japanese and will not go online and make off the record remarks along these lines as they have absolutely nothing to gain by doing so.
