These were on exhibit at our Yankee Pole Cat Insulator Club meet in Milford, MA on July 18, 2015. Among this grouping were a rainbow of colors and a couple exotic pieces respective to Russian glass insulator production that I did not know about. Bob mentioned two or three that he had were one-only-known colors in their particular styles. Separate postings of these along with another view of his table exhibit can be seen, click "next". None in this picture were for sale.
