Given the changes in AMT ownership over the years, and in particular the apparently haphazard handover to Lesney Matchbox, I doubt there is anything like this in the corporate history file. If anyone would know, it would probably be John Mueller.
Even if it did exist, I am pretty sure it would be useless today given all the EPA mandates over the years that forced changes in our beloved spray paint lines (Testors, thinking about you in particular circa early 1990s...).
Still, to your point, David, sure would be cool....TB
