Yep, the 05328-60038.board was definitely used in the 5328A counter. I'm thinking that assembly was in the early serial numbers of the counter.
I'll send the manual pages to you by separate email. That should get you headed in the right direction.
Good luck with your project!

No, the number etched into the board is 05328-20027. It is very clear. On
the other side of the board is an ink stamp which reads 05328-60038. Is it
possible that the stamped number is the assembly number while the etched
number is for the board itself?
Anyway, There are a number of complete manuals for the 5328A & B counters
