I have found that you can use the UNIVAC news for research, but it takes
some time. They often had deployment / sales announcements that are useful
to learn what was sold and when. If you know what company or industry the
component you have came from, you might be able to find a sales
announcement about it something similar. This might help you determine who
typically bought what, and you might get a clue as to the origin of your
component that way.
Nothing known about it’s providence, at least as relayed to me. Don’t even know if its
active life was in the local region or it it was transported here after decommission.
Granted that knowing of an 1108/6 that was used locally could have been a probable source.
Local region is Victoria, B.C., large enough for such a machine to have been around but
not like a really large metro/industrial area.
You may have ruled other UNIVC systems sold in 1971,
but are you sure what
you have is not from a 9300 or 9400 system?
Here is some info and a few pics of 1971 UNIVAC 9x00 cards. These were
EBCDIC and compatible with IBM, you can count the bus pins of your
component to verify its likely system.

The 9xxx series machines apparently actually used plated-wire memory (!), as well as being
8-bit byte based and with smaller memory modules
(increments in mem capacity), so not a good fit with this module.
I did look into other univac series, but in the web page I just listed the ones that
seemed more likely to have a chance at being a match.
