Last week's three-day Formula One test at Spa was quite an occasion, if only because it was the first such event at the spectacular Belgian venue for a very, very long time.
Back in April 1983 the revised track, already in use for some four years by F2 and touring cars, played host to F1 cars for the first time. It was a month before the first Grand Prix, and the new pit buildings before La Source were still under construction.
Many of the drivers there that week had not driven at Spa before. Indeed, anyone whose F1 career fell between 1971 and '82 never got the chance to sample the place in either of its incarnations.
