I was looking for more info anyone might have in this gun. It's a Belgian Bayard arms 12ga hammer gun, not as old as it seems. Seems to be a mid range gun. From the proofs it seems to be only black powder proofed and probably late teens early 20s. The marks contradict each other a bit based on the charts I've seen. It says "damascus finish" but im not sure if that means It's damascus or if it was finished to imitate damascus, I tried some acids on it and couldn't get any faint pattern to show. Id like to shoot light smokeless loads in it for convenience, but obviously not if it's a black powder only gun. If anyone can provide any more info in the proof or bayard...
