P3D Sputnik lens designs

[Marco Pauck <pauck@xxxxxx>]

Yesterday I acquired a new toy: a Sputnik (LOMO version).

One of the first things I did afterwards (beside cleaning, tuning,
finishing and shooting the first test roll of course) was to search
for all available information on this beast. I already had bookmarked
the very helpful pages by Greg Erker (http://www.angelfire.com/ca/erker/page3.html),
Sam Smith (http://stereoscopy.com/cameras/hack-sputnik.html) and
others.

In addition, I'm right now in the process of browsing through all
185 Sputnik-related messages in the mailinglist archive
(http://www.pauck.de/archive/mailinglist/htdig/htsearch.cgi?words=sputnik&method=and&format=long&sort=score&matchesperpage=50&config=mailinglist&restrict=&exclude=),
and will probably summarize everything I've found by creating a new
web page.

However, one question remains unanswered:

Kadlubeks camera catalogue lists versions with two different lenses:
- Industar T-22 4,5/75 with shutter speeds 1/15-1/125
- Industar T-35 4/75 with shutter speeds 1/8-125
I've never seen the later version (only some earlier with the T-22
but shutter speeds 1/10-1/100). Is the T-35 the same three-element,
anastigmatic, single-coated design as the T-22? Any clues?

To add one more question: Can anybody map serial numbers (mine is
025050) to production years?
