My gun is a Webley-Pryse. In "The Revolver - 1865-1888" by AWF Taylerson, he discusses the Pryse patent as it applies to Webley revolver actions, not the frame lock.
The 'pinch' frame lock was not covered under the patent and widely copied by the British and Continental gun trade.
A pal had a pristine cased nickle plated 'Webley-Pryse' with the Holland & Holland name on it and on the case lid label. It even had 50 originals rds in the case block. He foolishly fired off 6 of them one day in a fit of willful stupidity. C'est dommage ... ;>( It could have been mine but for the lack of $1500, a small fortune at the time.
The RICs (their Custer connection notwithstanding) have never much appealed to me or some of the bird's head Webleys. An ex-wife once had a collection of 24 Brit revolvers, all .450/.455s. Alas, when we parted the guns were sold off, many of them going to a collector in NZ.
Capt. John - the buddies I'm talking about are Canucks, not Americans. Many are not as historically aware as you might want to think, knowing more about US history and guns than their own, thanks to the movies.
Once I learn how, I'll be delighted to show off the whole fam damily of .455s I'm blessed to own. I'll be singing "We're Soldiers of the Queen, m'boys ...","We're marching to Praetoria ...", and "Rule Britannia, Britannia rules the waves ...."
