Double Orange Curacao

This rare bottle of Orange Curacao is in very good condition but somewhat of a mystery.  A large portion of the label is missing.  The capsule is completely in tact and reads "SIMON Aine Chalon s/Saone."  The bottle is authentic ceramic and completely in tact.  The weight is 4 lbs, indicating a very good fill.  There is no indication of the spirit's age.
