Your comparing your pistol to the other simply due to the name on the barrel Prinz Taxis. The other looks aged. I suggest you reach out to some well known dealers in weapons of that period. I see your location is Dallas so some of the Antique weapon shows on the East Coast in Pennsylvania, Massachusetts, etc are out of reach for you. Unless you want to try the one in Vegas in January. I'll see if I can come up with some old e-mail addresses. Like I said it looks like a mixture of original and more modern parts with the a more modern restocking of the wood.
