"Eurosports slotracing!
The Worlds and European Championships I had taken part in were organised by ESROC and later ISRA. But never FIA."
I thought you were talking 1:1 Eurosport series which was nothing more than watered down Can-Am.
Sorry for the pithy remark, but please be more concise in your wording.
BTW: My FIA license was held from '66 to '88. What and when did you race?
