Now I don't want to be negative, but I've been down this track, with My late Dad's Favorite 0-1" mitutoyo Mics, I estimate they wer[php]e made around 1970.
These were so important to me as he carried them everywhere, but he was never too careful with his tools and they had been wet, I used a similar tool to disassemble cleaned them carefully, spent many hours, but after everything I tried they just didn't feel right.
I ended up scouring Ebay and bought a brand new identical set still in box, which was by far the best thing I could have done, they look the same as his did and so I get the same emotional high out of using them, but I don't get angry at how he ruined them just months before he passed, effectively taking my keepsake, I know I'm a bit twisted but hey it's a huge loss, it's gonna do damage when your Dad passes.
The best results came after cleaning them with WD 40, and then stripping that out with acetone, i used a small amount of 25% phosphoric acid, to eat and kill the rust, then reassembled with a very weak solution of brasso and light oil to polish the thread back up, washed in Acetone again then oiled up. It worked to some extent, but they were never the same as I remembered them, they were the first set of Mics I ever used aged 9 or 10 so I knew them very well.
I tried to work out how to post pictures but I'm not there yet,
Best regards

Whatever it is, do it today, Tomorrow may not be an option and regret outlasts fatigue.
