Hi Vlad!
Thanks for your respects, certainly due to my age!

I understand what you want: to be as consistent and logic as possible. But what is exactly "Industar"? A complex working for military and industrial purposes? A simple factory producing lenses? A bureau studying optics for camera factories? The classification depends partly on the answers which I don't know (A new topic, perhaps?).
I think that the Wiki must be as useful and easy to use as possible. If now I try to know which original lens goes to which Fed body, I must have to know first the answer before looking for: Fed or Industar?
If we are strictly logical, we will have to put the 3,5/50 into the Industar list as it is named "Industar 10" even it is only written Fed. As for the 28mm, 2/50 and 100 mm, they could be the last Fed lenses. But who knows exactly where and by whom they were made? Really by Fed? Not sure...
It's why I prefer a classification which lies upon what is written on the lens. It's easier to use. But someone needs to decide and you are the Boss! My seat is much more comfortable!
As for the two entries, I thought that the principle of Wiki was to complete each other including for pictures. I don't have any numerics, so if there is a problem, don't hesitate to remove.
Amicalement. Jacques.
