More about this type of keyboard...
The so-called "bigfoot" Model F terminal keyboard was a detached variant of the Model F keyboard assembly found inside the IBM 5322 System/23 made especially for the IBM 5291 Display Station and features the IBM 5251 Display Station's beam spring keyboard layout. Looking like an enlarged Model F/XT, the keyboard features extremely enlarged bezels acting as a sort of palm rest and comes with three-setting adjustable feet larger than any other feet found on IBM keyboards.
