Bernard, I think you have the system wrong -- I had to rethink it myself,
as I made the identical mistake you are making.

When Sven wrote, "Digit 1 plus 5 stands for the year of manufacture", he
meant, "Digit 1 plus Numeric 5" or "add the number 5 to Digit 1".  Thus,
with his 6008, body number 404330018, you take the first digit -- "4" --
and add 5, to produce nine.

Digits 4 and 5, less 20, are used to define the week of manufacture.  In
the case of Sven's camera, this would be "33" which, less 20, produces "13"
as the week of manufacture -- probably the week of 24 FEB 89 to 1 MAR 89, I
reckon.

Best,

Marc
