The production year is 1982 and the 2 is dropped to reveal the aircraft #.
Hence 82-2654 is shortened to 654 on the nose/tail.
That much I know.
I recall my 7-level (maintenance training instructor) telling me that the extra digit is the production batch number.
So that would mean aircraft #654 was part of batch #2 in 1982. Can probably also be referred to as "assembly 82-2".
