1. March 725 [1] (John Cannon): Built for 1972 season for John Cannon and fitted with Oldsmobile engine. Raced in UK and US series 1972. Advertised by Cannon and Patrick Kay (Autosport 9 Nov 1972) and later appeared in Ecurie Santos adverts in 1973 and 1974 but not seen again. It is reported that the 725 was sold as part of a large package of cars to Australian Ray Gibbs but the 725 remained in the UK and was sold to Peter Bloore (Wallingford, Oxfordshire). Bloore later sold it to Ryan Hodges who sold it to his friend Jeff Luff but the dates of these transations are unknown. In 1986 it was sold to Richard Parkin (Retford, Nottinghamshire). Richard has sold the car at least twice, only to buy it back again. Parkin sold the car to Richard Taylor (Rishton, Lancashire) in August 2014, but it sat with him at his Autotune Ltd business until 2021, when restoration finally began. During the restoration, Taylor's customer Andrew Wareing admired the car and decided to buy it. The car was completed in mid-2023 and after an initial shakedown test, the car was first seen in public at Aintree in August.

11. Surtees TS8 [005] (Hervé Bayard): Built for 1971 season and run by Team Surtees for Mike Hailwood to race in the 1971 British F5000 series. Hailwood won the opening race and also at Mallory Park and Silverstone later in the season to finish second in the championship. Sold to Belgian driver Hervé Bayard for 1972, reportedly together with a works spare car. Bayard raced it in one early season F5000 race at Mallory Park, but his main focus was hillclimbing in Europe. He had the car fitted with a Cosworth DFV engine and competed in the French and European series, winning overall at La Bachellerie, Turckheim-Trois-Epis, Les Andelys and Soissons. He finished second overall in the European championship. Bayard also used the Surtees-DFV at the Rothmans 50,000 on 28 August 1972 but did not qualify. After the 1972 season, the car was rebuilt back to Formula 5000 specification and entered by Ecurie Bonnier (Geneva, Switzerland) for Rolf Tellsten in the F5000 race at Mallory Park on 28 May 1973 but he and the car did not arrive. Ecurie Bonnier had been taken over by Heini Mader since Jo Bonnier's death. In February 1974, Ecurie Bonnier advertised six cars for sale in Autosport, including a Surtees TS8 that was "chassis only". The Surtees was later sold to engine builder Louis Morand (La Tour-de-Trême, Switzerland) and was stored at Mader's workshop at Gland, Switzerland until 1978. It then moved to Morand's workshop and was restored to F5000 specification, with a view to Benoît Morand, Louis' son, driving it. This didn't happen, and the car remained stored until sold to Peter Hoffmann (Mainz, Rhineland-Palatinate, Germany) in 1982. Hoffman also did not race the car, and sold it in 1989 to Rainer Jacobi (Mainz), who restored the car and ran it in historic events in 1990 and 1991.
12. Chevron B24 [24-72-01] (Brian Redman): Built for 1972 season.

Badly damaged in a severe testing accident at Silverstone on 24 May when a tyre burst at Woodcote at 140 mph, and Thompson was lucky to escape with bruising. The car was written off, and Brodie acquired a brand new 1973 B24.

Autosport 27 Apr 1972 pp22-25 (by Pete Lyons). Motoring News 27 Apr 1972 pp13-14 (by 'AH' Alan Henry). Sport Auto Juin 1972 p48 (uncredited). Autocourse 1972-73 pp136-137 (very brief report by Mike Kettlewell).

Eleven cars were entered but only ten turned up: two Lotus 72s, two McLarens, two Surtees, two BRM P160s, Frank Williams' March 721 and the brand new Brabham BT37. Alan Henry on his F1 reporting debut gave chassis numbers for all ten cars. Mike Doodson had left Motoring News after four years to work for John Player, and the Track Topics pages were taken over by young Alan Henry. Incidentally, Autosport (20 Apr 1972 pp18-19) lifted the lid on the workings of the Formula 1 Association, then run by secretary Andrew Ferguson. It had started in 1964 with members BRM, Lotus, Cooper and Brabham, but had grown to include entrants and its new members for 1972 were Tecno, Marlboro-Austria, Marlboro-Spain and Eifelland, while Connew's papers had also arrived. There was no mention of Bernie Ecclestone at this point…
