Need help figuring our the VIN and Body/Style Plate

[guitarman56]

Hi all, new to the group and the new owner of a 1954 Pontiac Chieftain.  I've been struggling to decifer the numbers and figure out exactly what the numbers are telling me.  The VIN is P8ZH28332, which is the easy part, at least for me.  P=Pontiac, 8=Straight Eight motor, Z=1954, H=Hydromatic Transmission, 28332=the sequential numbers.  From there it gets confusing.  

The Body/Style plate has the following:

Style No. 54-2537 SD, which I believe indicates the car as a 2Dr Custom Catalina Super Deluxe Hardtop, but not 100% sure

Body No. P 2440 - can't find any reference for this

Trim No. 72 - can't find any reference for this

Paint No. 12 - one source said this is Biloxi Beige

On the bottom left corner of the plate has either 7 O P or T O P - nothing found for this

On the bottom  right corner of the plate has ACC. BAG-1 - and nothing found for this

So, any help identifying this information would be greatly appreciated.

Thank you
