I have a custom 50 cal flint lock, made by Bob Roller of the US. Bob Roller was a premier flintlock maker in the 70s and 80s. The gun has custom scroll work and was valued at 2400 US by contemporary flint locks. It has a crack wrist, but was professionally repaired. The year the gun was made is 1980. Local pickup only as it cannot be guaranteed for shipping by most shippers.
