Jim, With a collection like that you might want to research Glenn Erickson of Seattle. I was fortunate to drop by his shop when he was gathering frames he had made for a show. He did amazing artistic work.
I was lucky enough to see your Mattolini at Jon's place. I have two bikes with his complete drillium. I am really glad you saved the Mattolini. I hope someone saved his Samontana Masi.
All the best
