Reading Alan Hall's Action Man guide volume 3, it ends with a photo of Action Force.
Alan states that the AF teams included SAS and Enemy, plus 'Heavy Brigade' and 'Deep Sea' teams.
Why Alan's book, which is incredibly researched on AM, is so slap-dash with regards to AF at the end is a mystery, especially when you consider that his shop has a stack load of box-fresh AF for sale, presumably there since the very beginning of the range back in the '80's.
The point I'm making is that maybe he wrote this final part using some early series 2 Palitoy reference materials, back when the team were perhaps still being developed?
We known that Z Force was originally called Heavy Weapons Brigade.
''Perhaps'' Q Force were originally named 'Deep Sea' team.
''Possibly'' along the 'SAS' team and the 'Special Weapons' team.
It's all 'if's' & 'maybe's', I know, but thought I'd add it in to the speculation.
Sorry to dash hope Paul, but it's not really possible evidence, he has pretty much re-worded the text found in the 1983 Trade Catalogue.
In terms of the Action Force for sale, it won't have been sat on the pegs for 25 years, these were still being liquidated through some toy wholesalers as late as 1999, which is partially the reason they have had trouble appreciating in value when compared to other toylines.
