Yes! I got myself one. Very dirty, a bit rusty, without cable, with some sticky keys and with broken cable socket, but it was for 7 buck, so... I thought "Why not".
So I guess I'll need some help with restoration, and if anyone can tell me how to remove rust from metal plate, it'll be appreciated.
Will post some photos later. For now - it definitely a buckling spring keyboard, clicky, with that "ping" that IBM Model F sadly famous with.
P.S. Found some old articles about this keyboard. Seems it possible to program built-in controller to use XT protocol. Will need some further research....
