Europeans tend to overclean to American tastes. That's why antiques from over there are almost always in the white. Looking at the age of the wood, how it is slightly shrunk around the side plate. The aging around the metal pins holding stock and ramrod pipes. The details of the lock and other parts. You can get a good quality casting but without a lot of work, it is still not the sharp detail of the original. I don't know of anyone making castings like that frizzen for instance. It's helpful to get some experience working on these. I know how to make it look old, not as well as others, but I can make a restoration look period enough that it isn't jarring. It helps to know what to look for. The first thing to look at is the screws. I'll grant you that the lock pin screws are modern but every one of the lock internal and external screws is handmade and hand threaded not using a modern thread. There's not a doubt in my mind that the pistol is original. The sideplate is a bit odd. I suspect that when they cleaned off the rust they rounded the edges by accident and wiped off any engraving. If it had not been over-cleaned and had period screws on the lock and a less odd sideplate it would be at least $200 more expensive. I've tried to keep it's flaws accounted for in the price. If you are interested I can post it in the discussion portion of the forum so you can get other opinions and I can get photos of the inside of the side plate/wood and inside of lock and lock mortice in the wood.
