Those "date codes" are pretty much meaningless, and tell you very little about when the calculator was actually manufactured. I have four HP 80 calculators ranging from the first version 1 all the way up to the last version 4. They all have exactly the same S/N prefix "date code" of 1247, but clearly they were not all manufactured in the same 47th week of 1972. I suspect that HP simply printed out a bunch of blank S/N labels with the "date code" somewhat close to the printing date, and then added the sequence number that follows the country code during the actual production runs. One thing is certain; the calculator manufacturing date is later than the "date code." Notice that the 1333A on your S/N label is printed in a different font than the sequence number. BTW, the S/N on my HP 65 is also 1333S....
