For auction this week:
http://richardedmondsauctions.com/catalogue-new/?lot=2113Series III saloon, chassis no. 1917.
This car "was delivered to coachbuilders Castagna of Milan one week after it was built, and they modified it in very ingenious fashion – it retains the original steel body tub, and therefore its structural rigidity, but the traditional ash-framed saloon body has been built on and around that."
No connection to car or auction house.
