Wow thats something that you knew Jeff Cooper. There was someone I admired. Love his outlooks on life. Miss his articles and teachings.Terra - in one word, no.
I know Robbie, he's done work on my stuff too - once. Decades ago, Jeff Cooper recommended him to me - Jeff used to have everything done at Robbie's place (ROBAR). Before he went elsewhere for reasons I won't go into unless asked - same for me.
