I'm afraid if those method would damage the mechanical in some ways. Asahi must have a good reason to not mention those MLU.
So is about SP500 allegedly having 1/1000 speed over the 500 mark. I guess.

I recently picked up a Honeywell Photo Products guide from August, 1975. At the back it has a “Custom Products and Modification” page where you can get a Mirror Lock-up installed on these Spotmatic models: F, II, IIa and SP500. You can also get a Matt Focusing Screen as well.

Just wondering if any of you have heard of this option and ever seen/owned an example?
