E-mail received this am from CSCC:
"Dear Competitor,
The headline event at the Spa Summer Classic this year, is again the Spa 3 hours race into the night, running for the second time. The new for 2016 event was fully booked last year and we expect it to be the same again this year. The Spa 3 Hours race is for cars confirming to FIA Appendix K specifications up until December 1976. Please find attached a copy of the regulations.
You can now enter with the CSCC and we have set the price in Sterling at £1595 against the Euro price of 1850.
If you have a car that does not have papers but otherwise you think would be eligible, please contact the office to check. Despite the currency change this is great value when compared with the Spa 6 hours race, which we understand is already full for 2017.
The remaining races that the CSCC will be running at Spa this year will be available to book soon. All series will be able to attend but remember that you do require a minimum National A race licence to be able to take part.
Kind regards

I have no idea whether it's better to apply direct or through the CSCC for the 3 hours, but you have a choice.
