Princess Elizabeth
The first few had Roller Pick-ups, but the majority had the Plunger Pick-ups illustrated.
This model has the Mark 1 Chassis with plastic wheels and was fitted with the XO1 motor which has a disc commutator. The chassis was fitted with a laminated sheet steel weight.
This model also has a lead weight glued into the body. This is original and was fitted at the factory to try and improve the contact between the rails and the sprung pick-ups.
