A few new dates appearing:
Alfa Romeo Championship Association have announced that they'll be at Silverstone on the date CSCC should have been there, before being bumped for the (subsequently abandoned) re-arranged WEC meeting - weekend 22/23 August - so I'm guessing that its actually a 750MC event.
CSCC have announced today that they'll be running on the 15/16 August at Snetterton 300
