Hi Rikkn and welcome to the Forum.
Your gun is not a Snaphaunce, but is a matchlock and most probably of Indian origin. The marks shown are likely to be armory marks. Can you please post a clearer pic of these? Other Members will no doubt expand on, or correct my comments.
Regards Stuart
Sorry Rikkn, I misread your text regarding this being a Snaphaunce.
Would like to see pics of that one though when you get a moment.
