These are super-nice original used IBM Model F XT flippers/pivot plates with their original buckling springs. Just two sets are available!
They were all built to IBM’s original quality standards and are from one of the very first models of Model F keyboards produced, originally part of IBM’s Personal Computer (5150 PC).
You can order this set if you want an even more vintage typing experience on your keyboard.
Ordering the set eliminates the new flippers and springs that would otherwise have been included with your keyboard order. You would get these instead of the brand new flippers and springs, which would not be included in your F77/F62 order. This order includes factory installation of these flippers in your F77/F62 at no extra charge.
