Thanks for the complements guys.
As I mentioned, this little rifle was one of a seven gun auction lot. I bid an amount that I felt would be a reasonable price for the Webley alone and ended up winning the auction for about 20% less than my bid! A good day all in all I must say.
The rifle was originally chambered in 300 Rook (determined by the proofs on the barrel) and has been rebored and chambered to 357 Magnum. IMO, not a bad choice if the original bore was junk, which many are. Now, I can choose between the power of the 357 or the milder 38 Special, which, by the way, is very similar to the 360 Rook. These "small" Webleys are actually rather large when compared to other rook rifles and a cartridge with a little more zoot suits them well.

Chris, you mention the Wyley Webley. The Wyley was a predecessor to the Webley falling blocks. It had what I refer to as a Pivot Block rather than a true falling block. About the best way I can describe it is that it is like a Rolling Block which opens to the right side rather than to the rear of the action. I guess the most similar mechanism could be the Soper but the activation is totally different.
