Nice restoration there, I'd have to check in the set but I think my French Meccano/Scalextric Matra and Alfa are the superboost variety, picked up at a car museum in mougins in the mountains behind cannes around 1989.The 1972 33 was a good car,but up against the ferrari 312 pb fleet and the French government funded matra ms 670s it was an uphill task,that 1972 season narrated by Vic Elford and Mario Andretti is superbly captured in the Michael Keyser film the speed merchants, I think it was available first as a VHS video, my copy came as a dvd with the fly Toad Hall racing Targa Florio entered porsche carrera RS, fly also produced the 1972 le mans entry. Its well worth digging out a copy, the late much lamented museum Rosso Bianco in Germany near frankfurt had a stunning collection of 33s,I was fortunate enough to visit in 1990 when busy with trade exhibitions at the frankfurt messe.
