WIN1894, The proof marks for a gun are always stamped on the barrels, as that is what is being "proofed". So it is any and all marks on the underside of the barrels, on the barrels flats and on the barrels themselves forward of the flats, that is important for us to see. Also, in the case of English guns, it is helpful to see any and all labeling of the gun for the makers name and the makers address, often inscribed along the top rib, just forward of the breech.
Finally, without meaning to be critical, fuzzy pictures don't help. If you want help, first you must help yourself. And that means taking good, clear, close up pictures of all that I have just described, as well as the rest of the gun, so accurate assessments can be made of both the original build quality as well as the current condition.
Take the pictures outside, on a cloudy day. Don't use a flash. We need to be able to see what you see.
