Yes, you are both right. It is no genuine Zeiss Sonnar. Most of the details are wrong. Even the name ring is fake. The serial belongs to a range of lenses that all share the same non-Zeiss origin. German black-market made.
Another irregular production Sonnar

I agree that little about this lens looks legitimate.

US $418.00Another odd-ball irregular production Sonnar. Looks like a war-time barrel with Zeiss West style of engraving as Rauber has pointed out on other lenses. Serial number does not appear in the 2023 version of Thiele's book of CZJ lenses. Whaddya think?

Wow. I guess my Mint condition, authentic wartime Sonnar in LTM would fetch a lot more these days than what I paid for it.

It sold for less than I thought it would. At the same time, I realize that the number of people interested in antique, potentially historic lenses is decreasing as time passes.

Some day they will all end up with one person? Draw Straws for it?

Let me guess who that will be. Hmmm. Is that person a camera buff? Does he hang around camera boards? The highest hurdle, can he code FORTRAN? I think I have an idea of who it will be. ;o)

I was sent another Sonnar T transition lens to work on- and made me realize my "276xxxx" lens is mis-engraved, and should be "286". It is nearly identical to the one I just took apart. Some of the 286 batch of lenses ended up as Jupiter-3's, including my perfect glass 1950 lens. That lens is identical to wartime 5cm F1.5 Sonnars, and has the SN in the rear fixture to show it.
The transition lenses - my "276" and the just cleaned 286: the rear triplet is the same as the post-war CZJ Sonnar T 5cm F1.5 lenses. The latter- different body, barrel, and fixtures. BUT- the rear triplet is the same.
Compared with my KMZ J-3, the diameter of the rear triplet of the transition lens is smaller.
And that barrel?
No retaining ring for the aperture- the barrel screws directly into the mount with TWO SETS of threads.
Rear Triplet- matches the later East German CZJ SOnnar,
Number of grooves in the Aperture matches my lens.

I have a 298 series Sonnar f1.5 with a rear element like the above. I also have a 286 series Sonnar with the standard WW2-era type rear element. Looks like CZJ was using several different configurations when they were scrambling/struggling to recover from the destruction of the war.

So these lenses were made between 1945-1947?
are the aperture ears the only thing that’s not “parts bin” about these?

I believe the middle triplet is the same- at least I've interchanged them before. The front element, and retaining rings for the middle triplet and front element are also the same.
The rear triplet- reduced in diameter to conserve glass?
