The cheapest model comprises a com.plete outfit, which includes air pump, flywheel and pulley for a Whittle belt drive, filter and pressure gauge, and costs £9 7s., the pump being designed for attachment to the vehicle itself, or for stationary use in workshops.
Model No. 2, which is suitable for inflating the largest giant pneumatic or ordinary car tyre, carries a similar equipment, with the addition of a standard electric motor for 200-250 volts D.C. This unit, is monnted.on a substantial cast-iron base provided with rubber-tyred swivel wheels and 16 ft.' of tyre flex cable, an adapter fos a lamp -socket, and 16 -ft. of delivery hose' with a valve connector. In this case the price is £25 10s. The pamp is made entirely of metal
