I purchased a Purdey during Covid, the safety and triggers springs had been compromised by some incompetent. I emailed Nick, explained the problem, and he put me in touch with a person in Purdey who, after much cajoling about the global shutdown et al., agreed to sell me the springs. I took a photo of each and sent it off. I phoned Purdey with my CC, “no returns” they said, and a month later the parts arrived via Royal Mail, certified. I had a competent smith in Vermont put them in , who subsequently told me I was fortunate because Purdey does not sell parts. I mentioned they did ask if I needed mainsprings but I said no, to which he said “you should have said yes.” No problems to date. Count my lucky stars.
