The Prewar Jena sequence in McKeown was generated by the noted optical
designer and theoretician, Ed Kaprelian. We have only managed to improve
upon this in recent years with one more bit of data -- from some
information posted here on this List a few years back, we know believe that
1938 runs from 2266087 to 2527984.
The Postwar Jena numbers are a continuation of the Prewar numbers but our
understanding of them is quite soft. I would guesstimate something along
the following lines:
late 1945 3,000,000
1985 50,000 (Jena deleted "10,00" from the serial numbers at around
1990 750,000 (production ended in 1990)
The Postwar Oberkochen serial number run is vastly complicated by their
apparent custom of assigning number blocks to specific lenses, so that a
consecutive number run might take several years to see the light of day.
Further, there are several large blocks in the middle of the 2,000,000
range which should fall into the late 1950's but which clearly do not, as
these are on SL66 lenses introduced in 1966. There is good data available
in Kuc's CONTAFLEX-CONTAREX and in Nordin's HASSELBLAD SYSTEM COMPENDIUM,
data obtained from Zeiss, but the two schemata do not agree for the period
1959 to 1966. It is all most complex!
I have a rough table for Postwar Oberkochen lenses developed but it needs a
LOT more work!
