Tower and Sword Neck badge

A very fine gold ( no hallmark) neck badge for the Order of the Tower and Sword as bestowed by the Portugese Royal Family to high ranking British military officers in recognition for serves to Portugal in the Napoleonic War.
The badge has a 2cm fracture along the base of the tower presumably as a result of being dropped at some point in time but which does not detract from the appearance and is only visible under magnification. Nonetheless an exceptionally rare neck badge in very good condition.
