Without laying hands on it and with the quality of the pictures taken into consideration. To me (and I'm no expert) it looks like an artificially antiqued replica from India. The frizzen appears stamped, not cast or milled, there is no ram rod visible, the pan appears flat (or very shallow) and I think I see paint on the ####. The jaws look a little dodgy as well, where do you put the flint? The screw is right through the middle leaving no room.
Again, just my 2 cents and it is hard to tell from pictures.
