Dick Knight lived local to me. Yonks ago (80s) he did a refret on my old Travis Bean and a neck shave/middle pickup install on our guitarist's Les Paul. He had a load of Billy Bremner and Nick Lowe's kit in when we visited.
*Point of trivia? Dick Knight only had one good hand and was missing half of the other.
That's cool! From what I've found out, Dick Knight did a lot of Les Paul re-topping in the '70s which tricked a few players. He would take late '60s or early '70s Les Pauls and stick a flamey maple top (and bogus '50s serial number) on them. His work isn't as widely documented as John Birch's for whatever reason, which is a shame. You don't roll out of bed and make a bespoke double-neck guitar like that without a lot of experience along the way. He made a white Les Paul-style guitar for Dave Brock of Hawkwind, and a mahogany double-neck Strat body for David Gilmour, but beyond that I've not seen his work mentioned much outside of 'Les Paul faker' infamy.
