I had the pleasure of interviewing John a couple of years ago regarding the triggers he supplied Geoff Hart, who arguably made the best TR conversions from a No.4 that has been done. Bert Whitaker's "Special" coming a close second!
John's No.4 sight is something to behold, IMHO better than then any of the P-H or AJ Parker TZ 4's, he also built a TR action in the mid 1980's, had he not had an order from South Africa for 25 sights then the Swing would have had some serious competition at Bisley.
My Hart No.4 conversion fitted with a
Brindles trigger, incidentally Johns house name was
Brindles (not a lot of people know that!)
