Yeah, I am looking for some less common MX variants for sure, I did try being as clear as possible that what I am looking for isn't stuff that is easy to come by. Mostly it's all stuff that was only available on some very scarce stuff made between 1984 and 1988.
I do have some MX linear clears, and would LOVE some more of them, or even better yet the white (looks like the current MX white opaque) with even lighter actuation. Of course the MX grey click is even more rare as far as I know only found on a few early 80's original era white click switch boards as a space bar switch. The 'easy' ones I want are the clear top Nixdorf blacks if that helps put a perspective here.
