Wow! That is an awesome piece! It is unique for sure. I first thought it might be an old phone station, but I see no holes for wires. If it's original, it is surely special, unique and valuable.
We can only take some guesses here on this site (or any site) so I highly suggest that you take it to 2-3 local antique dealers to find out it's age, value and origin.
I think you have a prize with that item if it's more than 150 years old.
