I've got two of the old beasts...
Both have been converted to run .45 ACP, more or less.
"Less" means the Mk. I has the cylinder faced off to acccomodate 1/2-moon, but NOT full-moon clips. That means only the outer half of the radius, which puts me in mind of an OLD conversion. Seeing as I haven't actually GOT any half-moons, I've never run this gun. However, since it's only partly faced-off, the center section of the extractor star will still locate and extract thin-rimmed .455 fodder, should I ever be so lucky as to locate some for a reasonable price. I'm not holding my breath, and since this 1888-vintage gun really wants blackpowder loads anyhow, I'll just hold off firing it until I can load up some black or equivalent-pressure loads with round-nose lead bullets to run on.
Now the OTHER choice is my Mk. IV, circa 1913 or so. This one's been fully faced across the back of the cylinder, and accomodates full-moons as well as Auto-Rim ammo. It's also wearing the grips that I made for it that rival some of Hakan's best, although you can't see but a tiny corner of them in this picture. So much for bragging rights.
This is the same pic, albeit MUCH bigger, should you desire a close-up. Slightly bigger than life-size, no less! You can darn near read the lettering on the frame! Thank you Sven!
This gun originally came with a 4" barrel that had been "Americanized" by virtue of the addition of a coarsely-made rib on tob of the barrel, with a pinned-in holster-friendly sight. The rear sight notch had a block soldered in and a new square notch cut into it. While solidly made, the craftsmanship on this added rib left much to be desired, as it was covered with coarse file marks, and the top surface was actually canted to one side by a few degrees. It looked home-made, for lack of a better description. "Hacked out", would also fit. Functional, yes. Attractive, no. If someone paid a gunsmith to make this thing, they should've found someone who took more pride in their work.
Additionaly, when the rib was mounted, it was pinned on, or so I suppose, as there's two ~1/8" dia. holes running from the top down INTO the barrel. That's right, into the rifling and interior, where the pressure lives! Talk about HACKED! Despite the gun's inherent accuracy with this set-up, and a lack of any sign of issues with the holes, I was motivated to switch the barrel for the Mk. VI unit it's wearing now. I also just happen to be a big fan 'long toms', so the 6" length suited me down to the ground. I got the 6" barrel from Springfield Sporters for a whopping $30 as brand-new surplus, and it dropped right in, requiring only a small amount of stoning on the extractor cam to assure reliable function, i.e. so it would drop down at the end of the break-open movement after extraction. You can see the difference in finish from the pre-war blued frame to the war-finish parkerizing on the barrel.
Surprisingly, with the moly-coated RNL's I typically run this gun on, it has proved to be one of the more accurate revolvers I own. Although it shoots about a foot to the left at 100 yards, it can happily harass a two-litre bottle with about a 4/6 hit ratio after a couple of sight-in shots. That's about a 6' group at that distance when I'm having a good day, with most issues being vertical stringing. (The above pic is shooting offhand at 100 yards at a milk jug. I stunk that day, and wound up killing the jug with Sven's Valtro. On the second magazine. I'm outta practice,)
My nominal future plan for this gun is to load up some Auto-Rim cases with 250- or 255-grain RNL's at .455 speeds to duplicate it's original intent and to preserve the old gun's frame dimensions. I haven't got a Prideaux Quick-Loader, but I DO have a couple of old (But still in blister packs!) HKS speedloaders for Auto-Rim. They're for 1917's and M-25 S&W's, but they fit the Webley, just like the moonclips do. I think I'll leave the 6" barrel on it, and save the old Mk. I for the 4" "snubby" role.
Webley's have Style, Panache, History, and Character, just like a classic SAA. Their strange appearance is part of their mystique, and their Rube Goldberg, springs-on-the-outside mechanism is surprisingly simple and robust. Internally they're amazingly efficient, with all functions running off the mainspring with a minimum of parts. And being .45 caliber, I feel just as well-served by one as I would with any more modern design. I'll pass 'em on to my kids, and I hope I get a chance to buy another 1 or few.
