I know, because we have researched every angle already and came up empty.
I want the proof in writing, opinions mean nothing.
Chinon manufactured for example the very last version of "Kern Macro-Switar 50/1.9" which is M42 screwmount.
Only 83 were produced worldwide (and almost all sold in Switzerland, so not very well known, it also was very expensive, i.e. SFR 1500!)
It actually was based on the same lens body as the famous Chinon Japan made 50mm/1.7 Macro (not a true Macro but at least nice 1:3)
Also Chinon Japan made the 55/1,7 Macro and ... if I remember rightly, the very first AF-lens with inbuilt motor.
I know it is an old thread but ended with speculative arguments based on... well.... "pouring empty into the void"
It is the same empty arguments about Chinar: Chinar belonged to Chinon, yes, but it isn't the same as when Leitz had R-lenses made in Canada, they were made according to the same formulas as the German Leitz lenses.
Chinar lenses have nothing to do with Chinon lenses made in Japan, but.... not all Chinon made in Japan lenses were made by Chinon... that we do know for sure.
So ... Chinar belonged to Chinon as Seat to Volkswagen, and yet, Seat isn't Volkswagen but used VW knowledge and technology.
