Luiz, what make you to believe that
quote:
these papers are Xerox copies of the original drawings
?
They does not looks to me as copies, but may be.
My doubts increased after I enlarged grid with signatures on second picture; I believe that I can see dates from 1964. I'm pretty sure that in 1964 FED did not have equipment good enough to make such copies. I'm not even sure that such equipment existed at that time.
Also "FED 20" is not necessary a camera name, It could be anything. FED made a lot of other staff and all this staff can have FED name. "FED", not like "Zenit" or "Zorki", was not reserved only for cameras. Any part of FED production can have it.
Also drawings seem to show only "home made" parts what we have concern with: back plate connector and focal plate for lens. I do not see droving of any body part or focusing mechanism.
Would it be possible that research was only about this plates, not about building new camera?
Also lens.... I would expect different lens. But of cause lens could be replaced later.
Also for mere few hundred $$ you can find experienced draftsman who can make these drawings today in few days or less. I'm not saying that the drawing and camera are fake, it just a possibility to make fake is wide open.
We need at list some publications in press to assume that "FED-20" camera project existed.
