Pigments

I am interested in obtaining any information about pigments sold by
Fezandie and Sperrle, Tricon, Leebon, or Roberson.  Specifically, we
have pigments from these companies but no information concerning
their true chemical makeup.  The Roberson pigments date from 1969
and some of the F & S pigments date from 1976.  Any leads would be
helpful.
