Need keyboard for IBM 528x

The subject line says it allŠ

I have just been given an IBM 5285 Distributed Data System, together with a
5222 printer. It appears to work (it came with an 8² disk that contains some
user application, and the system can IPL off that disk, and brings up a
prompt requesting the current date and time), but I have no keyboard with
it. This brochure 
(http://bitsavers.informatik.uni-stuttgart.de/pdf/ibm/528x/G580-0274-00_5280
_Distributed_Data_System_Brochure.pdf) has a picture of the system and its
keyboard on the front page.

If anyone has one of these keyboards, please let me know!

Kind regards,

Camiel Vanderhoeven
