I can understand questions like this in a general sense. But we're also talking about mechanical/optical devices with moving parts that were hand-assembled, designed before computers, and likely "vintage" - ish, and may have seen careful use or serial abuse. So a forum answer may be a generalized starting point, but is likely (or sometimes, or often, or always?) not the correct answer for a specific case.
Like maybe 50% of the questions on this forum, testing such gear yourself will give you a definitive answer, an answer that addresses your own materials and workflow, and that addresses specific serial numbers vs. a general product range. All in about 30 minutes, including pouring chemicals and cleaning up after. A couple sheets of RC paper ought to do it. Might as well find the sweet focus spot of each lens while you're at it, right? Or find where a specific lens starts to degrade a print? Good stuff to know.
I think I have days where I'm a broken record around here (test…click…test… click…) but testing always seems to teach me a little more than I was hoping to know (like, the half-stop on one of my nikkors seems to be a 1/3-2/3 split). And it makes me feel a bit like a little lab-coat badass who is serious about my tools.
