Hello,
Looking closely at some early Jupiter 8 lenses in Kiev mount I can identify about 5 different types.
I assume that this has already be done before so please correct me if I'm wrong, and add samples.
Here we go :
Picture one Type1, Type1A
On the left, type 1 is pretty close to the ZK lens with the 'ears'. Besides it's the same without 'ears'. So, Two lenses : T1, T1A.

Picture two Type2
A comparison between T1A and the pretty common version of J8 (type 2). There's some obvious differences. T2 has a blakened outside filter ring (1), focusing barrel is not so large (2), mount manufacturing is slightly different (3)

This is great article! Would you continue to classify Jupiter 8M?

Jed, it is a great article, how come you posted it to forums though instead of articles section? I can repost it there for you later.
Thanks,
Vlad

Thanks lots !
Okynet,
Sadly I only own some samples between 1958 - 1962. I need later samples, so feel free to post pictures.
Vlad,
I agree the articles section is a better place, but I think we can improve the classification before. So feel free to post comments or pictures of your lens if they don't match my list.
Best,
Jed
PS : Vlad, I realise that I can edit the text and pictures in the articles section. So, you can copy my post in the proper section. Thanks !
