I just received this Webley & Scott Mk.1N pistol, after about 10 years of looking for one! Built in 1914 for the Royal Navy, it’s chambered in the semi-rimmed .455 Auto round. It’s a very neat, very unique pistol - the mainspring is actually a massive V spring under the grip, which as far as I know is unique to Webley & Scott autos. It’s a big gun - I pictured it next to British-contract Colt 1911 (also in .455 Auto), but the picture didn’t really bring out the sheer bulk of the thing.
