In the Best gun category, the maker would build what the customer wanted. GB Evans Purdey he inherited from Dr Norris was alight bird gun but had a Purdey nose and sideclips to action. When a gun was built for heavier loads it was often given some extra locking support regardless of whether it was needed. I had a WJ Jeffery with Purdey nose and somewhere I read they used that not for locking support but it stabilized the ejectors better. I don't like the Greener crossbolt but think the screwgrip action or hidden third fastener are cool. Now I want to know if the top extension on a Dickson RA is supposed to help with lockup.
