Been trying to find vintage mx black does this board uses vintage black?
What spamray said, it depends. I have personally desoldered at probably about 75 WYSE boards for harvesting switches, so I have seen thousands and thousands of these things. I think it also depends on what you are calling "vintage". I believe most people consider the ones with the larger cherry logo to be "vintage". On the ones I have seen, There were always variations with the logos on the switches, even on the same board. Some had a larger cherry logo on the switch top, some had a smaller one. Some had a beveled edge on the switch top cutout, some did not.
But I will say this. I never pulled a single switch from a WYSE board that looks exactly like the black switches I found on a modern cherry board. I think pretty much any WYSE board that has MX blacks is going to be from the 90s, maybe late 80s or early 2000s. I am off the personal opinion that any of those older mx blacks are different that modern ones, regardless of the logo on the switch top. The switch top is, after all, only one piece of the switch. A large logo "vintage" switch top does not guarantee the rest of the switch is vintage. Especially when you consider that you can find different looking switches on the same board, suggesting they were produced at least somewhat contemporaneously. So if you want to call the older switches "vintage" because they have different characteristics from modern production blacks, then I think that's legit because there are physical differences, at least with appearance.
As far as whether they FEEL different, I leave that up to the user to decide. I don't even have a board with blacks right now since I am a mx blue/green/ghetto green guy. But one thing that I personally believe contributes to a different feel is the springs. I think the older springs are ever-so-slightly lighter. I have no empirical data on this, but I have used both old and new MX black springs to put into mx blues to make ghetto greens. Yesterday I was typing on a board that used the modern production springs. Right now I am typing on a board that used the older springs. In my admittedly subjective opinion, I feel a difference. YMMV
Do I think there is a difference? Yes. Do I think it is worth a large premium? No, not really. Is there at least some placebo / confirmation bias going on? Probably. Is it cool to reuse old stuff in a meaningful way? I think so.
