Just found this thread; I have a 17,5cm Zeiss Tessar Nr. 123488 in a 1-1/200 Compound shutter with marked apertures f7.2-50, no serial number, but circa 1909-1910 according to the early photography website.
As the Original Post indicates, I have found no listing reference.

Thank you for sharing your lens.
Btw,’mine it’s not a real Tessar 4/3 design but a triplet 3/3. Rear lens is only a single element.

Amazing. Just checked mine and you are correct. Still time for a lawsuit?

Someone here with more knowledge can say that lenses with f/7.2 are 3/3 triplets and with f/6.3 are 4/3 Tessars, if I recall I read it somewhere.
I don’t complain about my lens, I love it.
If anyone can point out the early years of Tessar for reading, I will appreciate it.

Thank you.

Yes, I would be interested in that info as well.
The earlier f7,2 Zeiss Anastigmat was a very different lens.

I bought this lens out of curiosity, to put on a vintage Linhof camera.
My comment about the lawsuit was frivolous, however I wonder if the original purchaser knew what they were getting?
