Hi,
I sometimes see Nikkor lens mount (a few LTM) with a serial number at the back. What is this number? It does not match the lens serial number.
Any info would be appreciated. THANKS!

Per Rotoloni, "The Complete Nikon Rangefinder System", 2007, p. 216:
(referring to the number on the back of 3 example 50/2 LTM lenses) "Their meaning is not known at this time and the BM lenses are not so marked, only the SM optics."
Best,
Roland.

Some suggest the number in the back is the actual serial number matched to that particular lens.
But then some refer to the old Nippon Kogaku serial number system,meaning the first few digits represent the year and month of manufacture/design.
I wonder what the head-bartender thinks?

I have a number that is 906439 (for lens 811437), so there are lenses with the last 3 numbers as their serials.

the 1st 3 are the date 906. june of 1949, i have not seen the numbers on the 5cm f3.5, and i don't have a 5cm 1.4 to see if they have them, maybe someone else has one of the other lenses.
