Specialist Mouldings Hitorical Photograph

[My S1]

I suppose this questions belongs in a different Forum but I could not figure out which one.  You have all, most likely, seen the attached picture of the Sculpting/Fabrication crew at Specialist Mouldings circa 1966.  Does any one know if these craftsman (and secretary...?) have ever been identified by name?  I would assume that Peter Jackson might be in the shot and perhaps John Frayling.
