Potteries Motor Traction, following privatisation, opted to change their name to PMT. This move saw them open a new leg of their operation, 'PMT Engineering'. This department specialised in producing minibus chassis for their own operating fleet and for third party operators.
Probably rarest of all was the Knype, of which just thirteen were produced. I believe just two were sold to outside operators, with the remaining eleven being used - albeit short lived - in the PMT fleet.
Eleven of the type were based upon the Leyland Swift chassis, with a further two built upon the Mercedes Benz O814D chassis. There were distinctive differences between the Leyland and Mercedes Benz chassis; compare this photo to the Mercedes Benz variant above.
