I'd say that 8112 is a YYWW date code.
It is a YYMM date code.
Then how do you account for the "32" in "235-8532K"?
It IS YYWW (that is year and week)
so....235-8532 means 1985, 32nd week. That is why the K is there...
I agree that it is YYWW, but I don't understand what you are saying the
reason
is that the "K" is there? *Why is the "K" there?
weeK, to avoid any possible confusion to the date format used.

That's where I figured you were headed with the "K", but typically the YYWW date
code, as used on semiconductors for example, is used without a format indicator,
in fact IIRC some versions of the YYWW date code scramble the digits in one way
or another to obscure their meaning.

I wonder if the "K" might not have another meaning, such as a code to indicate
which of several factories the device was produced in? *If that is the case, the
fact that "K" is the last letter in "week" might just be a coincidence.

Could well be but so far only found K and was told so.

I was also told the first 3 digits where the factory ID,
can anyone confirm this?

Q: to OP. What country of origin is the cap from?
Could it be a code for country of origin? Like Canada, US...

I used to make a living selling P.R. Mallory
the 3 digit code is the manufacturer, 274
is/was RCA. And 235 is/was Mallory.
Ole P.R Mallory used to snap up companies
like RMC and Duracell. When he retired they
started selling off all those companies.
