Taken in 1988, in Tarmac\\\\\\'s Cawdor quarry scrap yard, this is a Hunslet prototype built in 1971, fitted with hydraulic transmission, and a Deutz engine capable of 58hp. She weighs in at 5 tons and is unusuall in having a transmission brake working on the side of a disc on the side of the gear box. Sales of the design never took off.
