I will try my best. 50-2569D is the year 1950 and body type 4-dr sedan deluxe Body No. P for Pontiac, Michigan plant 25404 is the production number. Trim No. 71 Dark Grey body, light and dark grey sidewalls Top is for convertible top color so N/A in your case. Acc: "The various letter codes found here identify the accessories and accessory packages installed at the factory. Only certain codes will appear on the Fisher Body Data Plate - those being the ones that affected how the body was built. Keep in mind that some models (Star Chiefs) came standard with certain ‘accessories’ that were not standard on others (Chieftains). Not all possible accessory codes were used on every car so equipped, since various accessories were ‘packaged’ for better sale ability. Also different combinations and sequences of code letters had different meanings, so interpretation of these codes can be confusing. To add further to the confusion, some code letters (such as 'X') were used in more than one accessory code and Fisher Body plants were not consistent on which codes they stamped into the tag. In this example 'BK', K = Underseat heater & defroster and K = Latex Foam Cushions." I will see if I can find anymore on the BA trim code.
