- Features are described to distinguish between cameras from a single production
run or in case of special interest. Back
- The coded serial number has 7 digits, № 6036942 for instance.
The first digit plus 5 (the key) represents the year of manufacture, in this example
6+5=11. When the sum is over 10, distract 10. 11-10=1. One has to guess the decade and
the century! Knowing this number belongs to a black 2.8 GX, the year would be 1991.
The digits placed in the second and third position, (in our example “03”)
are for factory internal use. They are called the Index.
The digits in 4th and 5th position minus 20 give the calendar week in the year of
production. In our example the digits 4 and 5 are “69”. 69-20=49
so the camera was manufactured in the 49th week of 1991.
The digits 6 and 7 stand for the sequential number of the camera. In our example
“42” means that the camera was the number 42 manufactured in the 49th
week of 1991 with an index of 03.
For those who are interested: № 6036942 was seen in auction. It is
a 2.8 GX ‘Helmut Newton Edition’ camera.
