Correct- Classic touring cars and Junior Saloons (running also) are listed at Silverstone INT.
-All those hours I've wasted driving the national on the Sim. How will I ever learn the track with such little time?

It is indeed on the international circuit. On the plus side only one corner (becketts) to learn!!

INT. circuit? Wow this is good news, think i'll be a bit down on power then but no reason to stay home then

Yes Brian it has always been Silverstone International, so although two Silverstone meetings one on the GP circuit and one on the International. Makes a change from the National circuit doesn't it?
