Pickfords Scammell NYE593E on the A5 at Llandegai with a transformer from Port Penrhyn to the pumped storage power station being built at Llanberis. (Merfyn Jones)

Mike Przyrembel writes ... Pickfords' very first 240-ton Contractor NYE593E, often teamed with NYE594E pulling 300-ton Crane Fruehauf trailer TM1277. Desperate cost cutting measures by Pickfords appear to include the use of ex-military tyres on the trailer.
