Does anyone know which open topper was in use at mile 6 for Guide Dogs charity? Think I saw most of the others but there was no sign of anything along there when I passed just before the roads closed.

Also is 6900 still in use with GNE? Havent seen it since Santa Bus guise and there's been a decent number of closed toppers on the Toon Tour this summer so presumably there's been limited open top availability?
