I'm not sure about Austin, but Morris Motors fabricated their petrol tanks in the 1930's from Terne Plate - a thin steel sheet coated on both sides with an alloy of lead and tin in the ratio 10% to 20% tin and the remainder lead - this coating allowed the tank fabrication to be easily soldered together and provide a rust proof interior once complete. As far as I'm aware Terne Plate is still available from specialist steel stockholders.
