Possible Colt percussion revolver in use by Afghan police in the 1880?

I came across some photos of 1880s afghan police, and one of them appears to be armed with some kind of revolver, possibly colt?

Maybe Colt, maybe not. While in Turkey I bought three colt look-a-likes, one may have been a Belgium Colt Brevete, the others definitely not. Patents were not observed in the middle east, they made whatever they wanted.
