A-833 Decode help please?

It reads: PP833 3007 0449 3007 = 10/21/1969 0449 = unit produced that day

0B164631 '0' = 70 model year, 'B' = Hammy plant, 164631 = sequence #


the next trans is a cast iron A-833 OD (at least I was told this when I purchased it).

It reads: PP8335229 5229 = 11/25/1975

It's a 10,000 day calendar see here for a calculator
