It is almost impossible to make meaningful comments without seeing pictures of the rifle. If possible, can you post pictures of both the front and back sides of the rifle, showing from the butt plate out to about 8 to 10 inches past the lock plate area? A picture of the signature would also be a great help. With those pictures, we can see the stock's shape, or architecture, and better estimate its manufacturing date by comparing to known guns. We can also see the quality of the stocking, mountings, and engraving to better establish the quality level of the gun and if it has been repaired or altered during its working life. These rifles are all individually made, no two are exactly alike, so to understand what you have and provide meaningful comments on its age, quality, amount of originality, etc., we really need to see pictures of the gun.
