That's Bull Dog to you, sir!
The real P. Webley & Son revolvers are marked on the top strap "THE BRITISH BULL DOG," and it's always two separate words. The Belgians and Spanish made lots of copies, and they always misspelled it as "BULLDOG." It's a handy thing to know, as some of the Belgian copies were quite good.
The gun is about the size of an old S&W .38 Chief's Special, and the real ones are also five-shot. The proportions are a bit different, though. The cylinder is fatter to hold that .44 caliber round, but shorter, and the barrel is longer by about half an inch. The cylinder, by the way, does not swing out. There's a loading gate on the right side of the recoil shield, and the ejector rod, which normally sits inside the hollow cylinder pin, pulls forward, then pivots to the right to punch empties out through the loading gate. It's the only thing on the gun that feels a bit flimsy, but mine's been working just fine for about 125 years. I'll try to be back with a picture to post.
The .442 RIC (Royal Irish Constabulary) packs about 250 ft/lbs at the muzzle, according to one source, which ain't bad for a black powder round from the 1880s. It beat the beejayzus out of the small pistol cartridges of its day, which were mostly rimfire. If you want to see one, watch the History Channel Tales of the Gun for the "Guns of Infamy" episode. It's what was used to shoot James Garfield in 1880. The show has its share of misinformation, and the narrator makes a point of mentioning that ithe gun sold for around $12.00 and leaves the impression it was a cheap Saturday night special, not mentioning that a dollar went a bit further then.
