This 30hp car is the oldest known surviving Austin. Austin's previous car designs, during his time working for Wolseley, had transverse engines with horizontal cylinders. His Longbridge cars had in-line engines and shaft drive to a live rear axle.

The original model was the 25/30 hp which had many features to be used on Austin cars until 1914, for example separately cast cylinders and side valves, with inlet and exhaust valves on opposite cylinder sides.

It is thought that this car was originally the station bus for Birmingham Parks but after conversion served for many years as the Longbridge Works ambulance. It was later re-built with this Edwardian-style touring body.
