Thanks Brian! I´ll take some pictures in the real world tis weekend.

Now the Industar 61 with two shims tightened:

New testing, with one paper shim. Still backfocus but not too bad... It´s an Industar 61 L/D from 1994 like new 1 meter at f/2.8 1 meter at f/2.8 1 meter at f/4 I will try to add one more shim thinner than this.

I've heard about that but I have no idea how to do it. But, thanks a lot!

As delivered is back-focus. With one shim... it´s difficult for me in my portraits to see if it´s slight back focus or slight front focus... I need to do a new test. With two shims it´s really front focus.

Testing with film are slow... but I added one paper shim and now is front focus :(

Thanks!! I split the optic module and I can see a "yellow" split-ring. Do I have to add a paper shim?

Is there a guide with the adjustment process for Leica?

Leica M7 with Jupiter 8. Kodak Tri-X My lovely Jupiter 8 from Brian :)

I lost the head of a micro screw in the aperture ring. I do not know how I could get it out... :(

Thanks Brian, The Tiffen cleaning paper are wet?

I know that the best is not to clean them, but how to clean an old lens when we have fingerprints and the glass or the coating is very soft? Summar, Summitar, Jupiters... I use a cotton swab with some cleaning fluid for lenses, but I do not know if it is the best option.

More detail and more contrast than the original sonnar and Jupiter 3?

All working properly now!

Does anyone know any manual on how to disassemble and lubricate an Elmar 5cm f/3.5?
