Rudyard, the former Purdey gunsmith comrade of David Trevallion, who immigrated to NZ about 1965 from London, about the time David came to the USA, is Robert Dollimore. I think he had a shop on the North Island at Rotorua. David is now 80 and cranky and opinionated, and can't get around as well anymore, but he's a hands-on non-academic true-fire seat of the pants gunsmith, highly respected. He was George Bush 41's personal gunsmith. He said Robert, unlike the lads at Purdey in the 1950's, early 1960's, was educated and in the class system of UK at that time, he took some heat from the boys in the gun-room for that. Wonder if he is still alive and active?
