Dead trademark registration for KP in the US dated filed on June 25,1962 and registered on March 19,1963 just for their precious (fine) or costume jewelry business. They worked in sterling, gold, and towards the end I have found jewelry marked rhodiant which is some type of plating that looks like rhodium.
