WOW!!!
Back pitch does not equal front pitch... Or is that a trick of the light...
If so, it's wonderfully pleasing that we didn't end up down that path.
Kindest regards,

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.
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.

no, manufactured in 1971 but probably a little
older in design. No

I suspect it is from an 1108 or perhaps an 1106, based on the reasoning
presented in the web link below. I’m a little curious for a firmer
confirmation though. 1108/6 documentation on bitsavers has been very
useful, but what’s there doesn’t go deep enough into the hardware to
provide a hard confirmation. Is there even an 1108 or 6 still in
existence?
The module, and what I’ve figured out:
