Armstrong Siddeley Dragon

The Dragon towed the gun instead of carrying it like the transporter. This is the vehicle which inpressed Captain Sheryer so much at TTS as a machine of great reliability, making a run of 100 miles in one day with only one involuntary stop, and was the first tracked vehicle to last 1,000 miles before track wear put it out of commission. The engine was an air cooled aircraft enginee.
