I bought the cherry clone keyboard for next to nothing from the friend (well, friend of a friend). I had one like this one long ago, before I gave it away... :-( The monterey one is very beat up, some keys are misaligned. So I didn't buy it. The Cherry clone has double shot keycaps. So it is worth it just for the caps. They are SP-thin though. The keycaps and the case are very yellow though. Will Oxyclean them later.
I may have to get some nickels action going later, since it is kind of an rare, unknown switch. Maybe I should desolder one to see what's inside. Oh, and it is plate-mounted.
