Jerry,
Actually I have been here watching tyne ALR site. I don't respond very much because there are so many knowledgeable gun builders answering questions before I can respond.
To answer your question about Mr Grillo. The last I heard, his collection will be on display at the CLA show this year. The entire collection was photographed and will be put into some kind of a book form. I believe Mark Silver is in charge of that. I hope it happens, it will be great to see all out rifles on display in one place. I hope that you will go this year it would be great to see you.
