How old was 'Marie Celeste'?

Nobody knows how old the fictitious Marie Celeste was. The short story J. Habakuk Jephson's Statement reveals nothing of the imaginary brigantine's history. It only tells of fateful events presented as taking place between Monday, Oct. 13, 1873, and Friday, Nov. 14, 1873, and resulting in the derelict ship's towing into Gibraltar by Captain Dalton's Dei Gratia in December 1873.
