OK. Roger that.
I was hoping to get them to offer some pictures of their various prototype
boards too as I am interested in those as well but find it hard to
visualize what the hole patterns and other routing really are on them.

Look at:
http://www.douglas.com/hardware/pcbs/breadboards/digital.html at
the bottom of the page (for hex).
They will still build them for you, at $100 a pop as long as you
order 10 or more.
Are they still in business? If so, perhaps they do not do it by email?
Numerous email to them from here have gone unanswered.
I'm another guy needing Unibus extender board(s) so if a group buy or
something similar comes together, add me to the list.
