I do remember you posted that once before. Either that or someone else posted exactly the same thing which I highly doubt. I wonder if that was a custom piece from the factory. A special piece by contract to a specific buyer maybe. Whatever it is I agree with Bob. It looks like that had to be made at the factory. It's a very unique piece which I have never seen before except for the one post before which I'm sure had to be you. My guess would be probably 1870s 1880s I guess. I can't see the whole thing in the pictures. Cool specimen though. You'll definitely want to hang on to it.
