Clint,
You can convey all this to Farhad if you are interested in the gun and bargain for a best price. I had told him the gun, in its condition, was probably worth about $400. But, I'd get a serious idea of what rifle cartridge and what shotgun gauge and chamber length before getting serious.
As to who bored it out: believe Kabul had an armoury that made all those Martini Henry rifles so abundant here. Fellow who owned the double rifle, might have had some problem with the right barrel and decided to have the armoury bore it out. Hard to say.
Regards,
Tim
