* Good, thanks; I suspected it might have meant "barrel," though I still can't reconcile the double-B. How did that happen?
* Aardvark,
The gun is apparently from the Caucasus, 19thc. style, though it lacks the big ball pommel that pistols from that area are famous for. Caucasian guns as a rule also lack trigger guards.
The stock does seem to be a replacement, as the barrel ("bbl!") decoration doesn't exactly line up with it (see bottom photo). The grain of the burl wood looks gorgeous in person. I'm told the shape of the stock is based on English and French patterns. The barrel is pattern welded damascus and has gold inlaid decoration incuding an inscription in Arabic script, which I'm still trying to have translated. Most likely Turkish or Persian.
I guess this would've been used during the Murid Wars (mid 19thc.), when several of the Muslim groups of the Caucasus banded together to resist several Russian invasions over a 30-year period. It's the basis for the ongoing war in Chechnya today. During my trip to Russia last month I developed a sudden interest in the Caucasus and its weapons. My next grab, hopefully, will be this pair of Caucasus pistols here:
* The capucine is obviously newer, but -- N2S -- how can you tell about the screws? Someone else made the same observation, but I for the life of me can't see the age difference.
