Here are the numbers! The shop said “…someone made a calibration ring from double side scotch tape, that's why it was not so easy to disassemble the lens - we had to apply very much force. But we had to, because we should calibrate it. From this moment the lens have calibration rings from paper as they should be and accurate infinity focusing. “I agree with TenEleven, this one looks legitimate. The numbers on the insides of the lens barrel are parts numbers, not CZJ serial numbers, per se.
Hello all - this is a 1949 ZK/J3 that’s being serviced in Ukraine. Are these numbers present in the Thiele book? Thanks in advance - I more than appreciate the goodwill and expertise here!
Thank you Dex. Hey, how and where is the Thiele reference book available?Here are the numbers!

numbers check out according to Thiele's book, part of a batch of 2000 lenses completed in January 1946, made in Leica screw mount
www.Lindemanns.de has this book available for about 60 euros. Shipping to much of the world appears to be about 30 euros, may be higher because the book weighs over one kilogram. I think that this is where I bought my copy 10+years ago.Thank you Dex. Hey, how and where is the Thiele reference book available?
Wow! Thank you! What a listing of books! Am I correct in saying this is the one commonly used in tracing the optical blocks that ended up in the USSR?www.Lindemanns.de has this book available for about 60 euros.

Yep, I think that this is the primary source of diverted CZJ optical blocks. The one Lindemanns has is the 2003 version, a revised version came out in 2011. The 2011 book came under criticism because Thiele included some interpolated data on probable serial number ranges that were not included in the 2003 version. I gave my copy of the 2003 version to someone on RFF after I got the revised version.Wow! Thank you! What a listing of books!

Are you using the last 3 digits of the serial to identify the batch?I have 1950 Jupiter-3's from the 272 batch and the 285/286 batch. Hard to know how many lenses from the wartime batches were actually completed, and how many remained unfinished are were carted back to the USSR to be completed as ZK and Jupiters. More of mine are from the 272 batch.
No, the first three digits of the CZJ serial number. The numbers stamped on the rear lens group fixture are normally the serial number of the CZJ lens, with the first digit removed. For example, my 1950 J-3 with zeiss components has 727386 stamped on the rear fixture, which corresponds to serial 2727386 for a 5cm/1.5 Sonnar as found in Thiele's book (i.e., it is a 272 batch lens)Are you using the last 3 digits of the serial to identify the batch?
Brilliant! And so my lens (846266) would presumably be from batch 284 (Dex did not give me the entire serial as recorded, just the year 1946). But if it’s 284 and in post-war batch, later than your 1950s, but with an earlier 1949 date ring, that would speak to the mixing of batches as they were assembled in the USSR. Which makes sense given the givens.No, the first three digits of the CZJ serial number.

That book is the right one. Fabrikationsbuch II from Hartmut Thiele. Beware it is in German. It contains all production batches of Carl Zeiss Jena lenses in a huge printed spreadsheet. It is quite easy to understand the content of this book but you might need some help with some labels. The linked book is the newest 2023 version. People all over the world write Mr. Thiele and point out some new serials missing in the book. So he updates it all the time and reprints it. He publishes his books all by himself.Wow! Thank you!

Carl Zeiss Jena engraved every lens block with the serial of the lens. That is the number you can find at the rear end of the lens. But CZJ left out the very first digit of the serial. You have to guess it. But we know from experience that in your case the missing number is 2. So your lens has the Carl Zeiss Jena serial 2846266. I already included it in my spreadsheet.Brilliant! And so my lens (846266) would presumably be from batch 284 (Dex did not give me the entire serial as recorded, just the year 1946).

The batch number in the Thiele book refers to the number of lenses completed as of a certain date. Rauber has incorporated the CZJ serial number production data into his database. The difference in the term "batch number" as used by Rauber is that he is basing his batch numbers on probable changes to the optical prescription of the various 5cm/1.5 Sonnars, i.e., not solely on the CZJ serial numbers. Rauber has done a lot of work characterizing the changes to the Sonnar prescriptionn over time that goes above and beyond simply recording serial number production dates from CZJBrilliant!
