Approximately 9,000 - 9,500 of the wartime Austin models were two-seater military 8AP tourers produced for the armed services and government, and the rest were four light saloons, six light saloons, two and four seater tourers and vans.
By the late 1930s, sales of Austin's big seller, the Austin 7, were declining and the 1938 addition to the range of the 900 cc "Big 7" did little to fill the demand, as despite its larger engine its suspension and handling were still rooted in its early 1920s origins.
The new car, which was displayed to dealers in February 1939, kept the 900 cc, four-cylinder, side-valve engine from the Big 7, now with a higher 6.5:1 compression ratio, but had a completely new chassis.
The model was unnamed and known simply by its RAC horsepower rating, plus the prosaic code that would not have been familiar to many outside the industry and trade.
The Military 8AP Tourer is recognised by, vertical louvres in the side bonnet plates of the car instead of horizontal ones, woodwork on the lower part of the windscreen, oil filled air filter, key-less ignition switch, closed wheels instead of pressed spoke wheels, pressed steel grille instead of sectioned cast grille.
The main differences were: steering wheel, chrome plated head lights instead of spray painted ones, horizontal air filter instead of vertical air filter, over riders on the bumpers, full back bumper instead of quarter ones, trunk handle, moveable licence plate carrier on the trunk lid, cast steel gear box instead of aluminium one.
The Austin chassis were reputedly shipped with guards (fenders), bonnet and grill surround pressings.
The largest and best of these companies known for the Austin 8 were: Ruskin, Larke Hoskins, Holden and TJ Richards & Sons.

The front window and seats were changed and some were fitted with a trunk lid, a feature which was not present on the pre war UK tourers.
