I am not totally sold on the 4th digit in the serial # being a 1. Could be a 4, but it looks more like a European 1, so that's how I recorded it. Sadly I no longer have the original e-mail that these photos were attached to, so I can't confirm what the owner sent me.
Whatever it is, it is a stunningly beautiful example of a Superba 1 bari. It even has its original H.Couf Artisit MP with it still.
