Hapsburg

I cannot provide you with a link, but I can tell
you it was released i 1993 by Silver Graphics.

Well, apparently it is also released under the name Bradley

My mistake

Is it possible to buy that font online somewhere without buying the book?

I'm not aware of any other digitizations of Bradley. If, however,
you simply require something close, a similar old typeface
called Germania was digitized by Dieter Steffmann as Germania
and by Jim Fordyce as Deutsch Gothic.
