I need help decoding the numbers on my munice. Trying to determine the year and what car it out of.

Main Case 3885010
Tail Case 3857584
Sidecover 3884685
Front Cover 3831752


Also P0531 & A172787 not sure what these numbers are either that were found on main case.

Thanks!!

Hank

The "P" stamp and main case is dated May 31, 1966
