The Ray Revell Offenhauser - the bulk of Australian Speedway historians and older Speedway fans agree it was most successful driver / car combination to ever run in Australia. 
The car was built with a flat back body in the U.S. in 1938 by Clyde Adams,  purchased and run by the Di Matteo Bros and later sold to Johnny Balch of the Balch Garage L.A.
A new body with headrest was made for the car ( circa 1946 ) by Balch team driver  
Bob Pankratz, ( Pankratz was trained in bodywork by Adams ). Later Balch sells car to millionare Howard Keck and Keck - circa 1948 - sells car to Aussie, Ray Revell.
 Driven successfully (for Balch) in the US by Perry Grimm and several other top line drivers. Revell shipped the Offy back home and he and the car began their fabulous career in Australian midget Speedway competition in the 1949 -1950 season.

Ray Revell

1911 - 1968
It's third life
In 1963 Ray Revell sold the Offy to Merv Neil in New Zealand and Merv fitted a Lotus Cortina engine. After Merv's ownership it went into the hands of Barry Butterworth who fitted a Ford V860 engine then on to Gordon Johns ( with V860 and Offy) who has one of New Zealand's top midget drivers - John Stanley drive for him. 
John later acquires the car and fits a grey Holden engine. 
John has kindly shared some historic photos of the car in NZ - running a Lotus Cortina engine with Merv Neil, a Ford V860 with Barry Butterworth, the Offy engine, and a grey Holden engine.
After Ray eventually sold the historic Offy in 1963 most fans thought that it was the end for the old car ......but it was only the start of a new and successful racing career for this marvellous old car in New Zealand.

Top NZ Solo rider Merv Neil buys the Revell Offy in 1963 and fits a Lotus Cortina engine and runs the car as # 77.
1964 - NZ midget ace Barry Butterworth buys the car - fits a Ford V860 engine and runs it as #91 (which was the original # of the Johnny Peers Chev II car Barry drove in Sydney).
John Stanley relates :

"This is the Barry Butterworth # 91. 
Red and white V860 powered 1964-65 Notice how the nose has a big hole cut out for new grille. During this season it blew a top radiator hose and Barry's legs and feet got badly burnt, put him out for the rest of the season."

1965 - 1966 Gordon Johns buys the car, paints it white and runs the # 30 with the V860 engine with John Stanley to drive. John says car was running longitudinal torsion bar rear suspension as Ray had fitted near the end of it's Aust. racing life.
1966 - 67 - car painted white and blue - Gordon Johns , with John Stanley driving, runs the Offy engine for the 1966 -67 season only. 
Car has rear spring suspension refitted and large nose aperture Barry Butterworth modified for V860 engine cooling.  
Ray with the Johnny Reed built  Supercharged DOHC engine - fitted to # 1. Similar to an Offy but with a separate cylinder head.  It was never run in the midget.  Word was Ray also tried it in his road racing car.
Merv Neil - NZ Solo rider convinces Ray to sell the car to him and the car goes to New Zealand minus engine.
 ( circa 1963).  
The car passes to John Stanley and John fits a grey Holden engine, paints it black and numbers it 75. ( not as Freeman tribute - he likes the colour black for midgets and just admired the Mackay cars ).  John says the car was most successful in NZ with the Holden engine fitted.

...from Chris Mcgee in the U.S.on Johnny Balch and his cars:
"I came across this information on Johnny Balch in Ed Watson’s 70 years of midget racing". 

“A major owner in midget racing in the post WWII era, Balch fielded cars for a number of great midget drivers including Eddie Haddad, Perry Grimm, Danny Oaks and Johnny McDowell, all of whom are in the Hall of Fame”

Considering fields of over 100 cars a night with the nation’s top drivers, the Balch cars taking the 1st. four places in the 1946 Gilmore points battle is incredible”

The car was brought back to Australia and restored by 
Eric Inmon of Port Macquarie NSW to be shown and run in Vintage/ Classic Speedway meetings.
