Just look at the PBP stormtrooper hard plastic, but there is also a kenner with a hard PBP body, but the legs and arms are soft kenner parts. The same with the cloud car pilot etc. etc.
The "Kenner" hard torso Stormtrooper has nothing to do with PBP. Latter produced white ABS plastic composition changed at one of the Asian factories.
oh, but was it not the same plastic as for stormie pbp ? to me it feels and looks like the same plastic
I do not remember where I hard read it, but I think I have read something about it was a mix up of wrong plastic parts mailed to the factory where they put the parts together and that it should have been soft parts they should have sent to the factory
