Nigel confirms that he still has the Leyland Panther which was, until recently, housed at the same Yorkshire location as WEX685M. The sale of the latter will help with the former's restoration
He tells me that it been a slow restoration job due to work and personal commitments. At the moment the exhaust manifold and silencer have been removed for repair and he hopes to continue with the work once the lighter evenings and warmer days arrive. So hopefully it will be seen again on the road again one day he says!
My thanks to Nigel for the information and photo which will no doubt satisfy Paul's curiosity
