Car 1: Built for 1973 season (red). Skip Barber: raced in US 1973; returned to March and later used as the basis of Cannon's '73A/75A'. First seen with Cannon from Pocono 1975 through Mid-Ohio (10 Aug 1975) with most of its original 73A bodywork. He skipped Road Atlanta and reappeared at Long Beach (28 Sep 1975) with a heavily modified car incorporating some 751 parts. Entered by John Lane. Later run in Tasman 1976, where it was described as:

'March 75, AM: March Formula 1 Chassis built 1975 as spare to works team. Sold to Cannon and modified in USA to take Chev engine. Used last year in US formula 5000 championship' (1976 Surfers Paradise program p7)

Then UK 1976, where it was described as:

'The March, sponsored by John Lane, was cobbled together "from a box of bits. I don't suppose March even know of its existence." It features a new 1973 F1 monocoque 1975 F1 front suspension, 1976 F1 bodywork, and "our own back end."' (Autosport 18 Mar 1976)

Then US 1976 (Cannon also raced the 73A/751 at R3 Watkins Glen, R6 Road America and R7 Riverside in 1976; and rented it to Don Breidenbach for R4 Elkhart Lake (25 Jul) and David Purley for R5 Mid-Ohio). Not seen during 1977 then possibly to Australia late 1970's/early 1980's. Crashed while testing in California in January 1977. Parts were used on a second, "duplicate", car.

The remains of one of these cars stayed with the Cannon family for many years. In 2004, Michael Cannon sold a tub and bodywork from 73A/2 to Paul M. Wilson (Los Angeles, CA). The car came with the original 73A/2 chassis tag and is green with a yellow stripe, matching the livery of the car prior to Long Beach 1975. So it appears the 'new' Cannon car - i.e. '75 AM' can be dated from Long Beach 1975.

Being rebuilt in 2004 by John and Graham Collins Fabrications (Santa Ana, CA) in 2004.

Car 3: A "new" car, described during the 1978 Australian Rothmans series as:

Re-built replica of successful March 73B brought to Australia by Cannon in 1976. New chassis with no number. Believed to be ex Vittorio Flammina chassis used in American F5000 races in late 1976. Not used during 1977 as Cannon did not contest Can-Am series with this car. Some body panels from original 73B that was crashed in testing accident in January 1977 in California. (1978 Surfers Paradise program p36)

The bit about it being the "Flammina" car (i.e. the 76A) is highly unlikely. The "73B" notation is also incorrect, as that was a Formula Atlantic car. However, we can believe that it was a new car, replacing the original 1975 '75 AM'. The donor tub is not possible to trace at this point and this car should probably be regarded as '75 AM/2'.

Subsequent history unknown but later sold to Graham Ritter and stripped of engine, gearbox corners, wheels and instruments. The tub was last seen on its way to New Zealand. It would be reasonable to regard this car as no longer in existence.

In March 2007, a car claiming this history was auctioned by Shannons in Australia. The car is said by Shannons to have gone via Ritter in 1977 to three further owners in 1979, 1986 and 2002.

Shannons' description of this car is available here.

Bought from Walter Hagstrom (Laguna Niguel, CA) in Dec 1988 by Michael Duncan. Said to be ex-Cannon, possibly '75AM'. Michael Duncan recalls:

The ex-John Cannon March F5000 I owned I bought from a Walter Hagstrom in S.Ca. It was a complete car from the roll bar forward, + the rear wheels + a pair of Morand valve covers. Not sure of the I.D. number, but it eventually was restored and ended up with Mike Yancheck in MI, and now is being offered for sale by RM Motorsports in MI.

Sold by Duncan to Ernie Spada about a year later. Paperwork with the car says it was sold by Duncan to Joe Carr then to Ernie Spada Jr then to Yancheck. Spada bought the car as tub, body, engine and gearbox and had it restored. Raced by Yanchek (#9 '73 March F1/F5000') at HSR Mid-Ohio Aug 1993. Sold by Yanchek to Dr VJ Mallya June 2005.
