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 > on the web, available for free download.
