I have an original late Westy wood headliner set in grey flecky finish which is cracked and chipped in places but complete and might be useful to someone as a template for making a new one out of ply. Collection only, St Albans, Herts. If no-one wants it, it will be binned in a few weeks.
It certainly wouldn't be the same as for a tintop. It is a large piece that goes over the cab, and then four strips which run along the sides below the upper bed.
