I've already posted two pics from this "photo session" of JW and DF with Tony Dukes, a vintage guitar dealer.
Here's a 3rd one, all from the same backstage dressing room. You can search back in the thread for the other two.
Tony sold Walsh and Felder a LOT of guitars, and most notably Felder's main 1959 Gibson Sunburst Les Paul Standard he recorded the solos for HC and OOTN on came from Tony.
