This radical design had an air cooled, five cylinder, sleeve valve, radial engine of 1247 cc mounted at the front of a tubular steel lattice frame.
When announced a price of £295 was advertised but by the time the car was exhibited later in the year at the London Motor Show this had risen to £350.
A. C. "Gus" Bertelli of the Grahame-White Aviation company was called in to give an opinion on the car and reported that a lot of development was required and the price was uneconomic and should be raised to £550.
[3] With a great deal of money spent on development and no sales to show for it something had to be done quickly and Bertelli was appointed Works Manager.
[2][4][note 1] This was not the end as the company was re-organised and moved to smaller premises in Small Heath, Birmingham from where the 12/30 was offered with a very wide range of coachwork from the Warwick 2-seater at £575 up to the Hereford limousine at £720 and Stratford saloon at £795.
