Commedia Figurine

This is a figurine of Columbine made by Fuerstenberg around 1770. It is marked with a very faint blue mark (probably a script F) I can't make out. Also an incised letter S and the number 281. She is one of the Commedia del Arte pieces and is in super condition. I found her after a long search in a very comprehensive reference book on commedia del arte figurines. The figure is 4.5 inches tall, about 2 inches wide and 1.75 inches deep. Please email me for more information or photos.
