I have had both. Far more Westleys than C&Hs. The Westley is head and shoulder over the C&H, from form to workmanship. Now, I am talking about Pre WWII as I have not looked at enough post wars. However, I doubt it changed. If a Purdey is a 10, and H&H 8.5 or 9 (some are bad about shooting off the face), I'd give a Westley HD droplock, 7.5 or better (because of the Westley "C" style lockup), then a Coggie about a 1. C&H varies a lot, some didn't have even a dolls head, much less a good third fastner on the action. I once knew where there was a beautiful C&H sidelock .450/400, but the guy couldn't sell it for boxlock price of a Westley because it was made after the war.
