Old keyboard layout... Is it still made?

I have a keyboard which is of a very rare (apparently) layout. It is
one of the earliest compact (NOT COMPAQ) keyboards, which appears to be
based on, but is not identical to the IBM 102-key "extended" layout.
For example, the F1-12 and escape keys are not separated into groups of
four, and the printscreen/scroll-lock/pause keys as well as the
numlock/page down/page up/home/end are all grouped just above the
numpad. I have a few, all of which are slowly failing (they're old) and
prefer them to any other layout. Is this layout still produced, or is
it something that must be special ordered (or custom made?)
