Thanks mashby, awesome pic. I never think of this during daylight hours, and you prompted me to do some more comparison shots of old and new Cherry MX switches. Please forgive the tater pics.
Left to right: (the only types I am selling are 1,2, and 4)
1. "Old" Cherry Black - Notice the medium font centered on cherries, whole logo is same width as the plunger, with beveled inside edge of the top housing. To me, that beveled edge on this type is distinctive, especially when you move it and see the light reflect of the shiny part of the bevel. It's definitely a different type of top housing from the other switches here, but I'm not sure where these fall, so I am grouping them with the "Old" Cherry Blacks. I saw someone call these "vintage" before, and they may be right, but I'm just not sure. From old WYSE terminal board.
2. "Vintage" black. Has the larger font centered on the cherries and the whole logo is slightly wider than the plunger. These are the ones I have seen others in the know label as "vintage". From old WYSE terminal board.
3. "Modern" Blue, current production. Here for comparison only. Notice the font is small, but centered on the cherries, and the whole logo is slightly narrower than the plunger. This is on a Rosewill RK-9000.
4. "Old" Cherry Black. Notice the logo is small like current production and is slightly narrower than the plunger, but also notice that the font is top aligned with the cherries, not centered. I have seen these called "modern" but if you compare it to the modern blue in #3 or to the modern brown in mashby's pic above, you can see they are not the same. But, those who came before me say that only the larger logo means vintage, so I am calling these "Old" to distinguish them from "Vintage" and "Modern". From old WYSE terminal board.
5. "Vintage" Blue, here purely for comparison (Read: NOT FOR SALE). Notice the larger logo centered on cherries and slightly wider than the plunger, same as "Vintage" Blacks. I believe this particular switch came from an old Dolch board, courtesy of jdcarpe.
