Great stuff Mr Orc, and well done on getting word to our cousins!
I have a few observations
I noticed that all Palitoy official paperwork has an L number attached to it
An Action Man message form I have has the number L33 (very low indeed), and a later Action man poster has the number L590.
For those of you unaware, the same thing is observed on Palitoy's Star Wars line - so my instructions for the Millennium Falcon have the number L296. The Kenner instructions don't have this number so it is a Palitoy exclusive feature.
As has been mentioned, there is a timeline of releases here, that allows us to date, relatively, the releases.
Gaps in the numbering would be explained by those numbers appearing in other Palitoy toylines (Star Wars, Action Man... er... what else?)
A greater man than myself could compile the whole of Palitoy's paper output using these codes.
