Interesting!
this lens has the aperture mark about 3/4th of an inch left of the distance mark, like mine has!
Mine is agreeing 100% with a Leica in focusing, something that 'normal' Jupiter-9s don't do.
Leica standard lenses are 51,6mm, the FED and Zorki-designated lenses are 52,4mm.
So, a Leica standard lens is in fact 0,9847 focal length of the FED and Zorki standard (51,6 divided by 52,4 equals 0,9847). To make a Jupiter-9 agree with Leica focusing, it would have to be 'shortened' to 83,7mm (85 times 0,9847). For which there is no room in the Jupiter-9 barrel, unless this is done at the manufacturing plant. There it's a simple procedure to extend the thread for about an inch more.
My Jupiter-9 came with a Carl Zeiss optical cell in it (284xxxx serial number) and a passport from the factory saying it was corrected to 83,7mm. To achieve this, the optical cell threads further into the lens barrel than with a 'normal' Jupiter-9.
When it threads further into the barrel, the aperture mark goes past the focusing mark, like this lens has.
As a result I'm pretty confident that this will be focusing correct on a Leica! Mine is, at least...🙂
