There are too many pitons, bashies and heads for me to assemble a comprehensive collection, so I don't try. If you would like to see a proper collection, I recommend Marty Karabin's site:
Karabin Climbing Museum: Pitons
Most of my pitons and heads were for my own climbing use. I have not had time to research these, and so I am only providing an image gallery at this time.
