No, it is a fairly well-worn Field's Patent falling block single shot. It was made for "RR Rodda & Co, #6 & #8 Dalhoosie Square, Calcutta"
I don't have it anymore, but it was an interesting piece. Caliber .500-.450 #1 Blackpowder Express. It was at one time heavily engraved with game scenes, but it had been carried so much the engraving was almost totally worn away. It was clearly someone's favorite hunting rifle, and could likely tell a lot of stories...
