hi!
I saw thatone before... Looks interesting, but I assume that it is a 19th century (I'm guessing here...) repro, made in a skillfull manner. Even the seller isn't sure.
In a way it looks a too textbook example.... However it is only my unexperienced opinion.
The seller has a private feedback and that is a private auction...

Personally I'd risk up to 500$ for thatone, but for 2550? You can get an original (naturally a heavily rusted one) for such price
