An Australian friend picked this up in Turkey and forwarded pics to ask what it is.

Okay... What is it?

Just a worthless wall hanger, I'll give'em $100 for it. ;)

I don't know whether it is some kind of abused Webley or what. With all the pits I'm wondering whether it is a cast replica of some sort. Though, I understand it does have a workable action. The firing pin on the hammer looks like the pointy end has rusted and become blunt.

So abused relic or homemade?

lol, I was hoping that it's a real webley rather than a cast replica. Wall-hanger for sure, but maybe worth something.

More than likely you're right about it being a replica.

Check out the thread down the page entitled "what the heck is this?"

Might be a Fagnus, as Jim Watson pointed out in that thread.

I had a fagnus once, a little ointment cleared it right up though. :D

This is a "Gasser" model 1880 cal. 11,3 mm, known also as "Gasser Montenegro". I am not shure about the country of origin for this particular revolver - it looks a little different from the Auistrian model. These revolvers were common in Balkans in the end of 19th sentury.

I think that your friend has this weapon (my best guess from internet search; I know little about revolvers from this era):

Alternatively, it could be an indigenous knock-off of the above Belgian revolver or even (possibly) this one...

Commonly known as the Pryse's Army Revolver (.45), it is a Webley made pistol patented by C Pryse in November 1876. It was a great favourite with Army Officers and has the distinction of being the first pistol to have a rebounding hammer (ie one in which the hammer, after striking the cap, rises far enough to be withdrawn from contact with it). It is sometimes called the 'Chinese Webley' due to the fact that the Chinese Government bought large quantities. It is said that the popularity of this pistol started Webleys, who were then emerging from the doldrums due to the success of their 'RIC' (Royal Irish Constabulary) revolver, on the quest for a really first class 'Break-down' self-ejector, which of course they eventually achieved. This particular pistol was sold by Henry of Edinburgh and London (Martini-Henry fame).

Almost every firearm under the sun has been directly copied (often individually hand-crafted) by Pakistani gunsmiths in the Peshawar / Waziristan region. This could be something similar...
