From the listing:
March Grand Prix Engineering began operations in 1969. Its four founders were Max Mosley, Alan Rees, Graham Coaker and Robin Herd.
March’s launch was unprecedented in its breadth and impact. APer building a single Formula 3 car in 1969 March announced that they would be introducing customer cars for F1, F2, F3, Formula Ford and Can-Am in 1970, as well as running works F1, F2 and F3 teams. The Formula One eﬀort initially looked most promising, with March supplying its 701 chassis to Tyrrell for Jackie Stewart. These cars were merely a stopgap for Tyrrell, who no longer had the use of Matra chassis and was in the process of constructing his own car; March was the only option available to him given clashing fuel contracts. In addition, the factory ran two team cars for Jo Siﬀert (Porsche were paying for his drive) and Chris Amon sponsored by STP (Chassis 701-1)
Amon took 701-1 to a rare Formula 1 victory in the Non-‐Championship 1970 International Trophy at Silverstone, as well as ﬁnishing 2nd in both the French and Belgian Grand Prix’ of that year. Amon came close to the elusive ﬁrst World Championship Grand Prix win in the car on numerous occasions but luck was not on his side.
