You can get lucky with old Cherrys, too. I got an G80-1000HDD a few days ago, manufactured in 1987, with MX blacks and I love it

And it's in absolutely perfect condition.
Are you looking out for these things to use them daily, or just to nail them to a wall or something? If second, even older keyboards may be more interesting, as they often have a very random and funny layout. I have a 1984 Future Technologie keyboard with prototype blacks, I tried to game and type with this for a while but it just gets too annoying, no arrow keys, capslock is switched with right Ctrl etc.^^
