Is that a Cessna 170 behind ‘RP? Looks quite tidy, whatever it is.

I think it is a Cessna 180 but I’m not quite sure about that. It was owned by Rolls-Royce restorers P&A Wood then (had their logo on the tail as well), Andrew(?) Wood drove the Napier Railton on that day I remember. I’ve tried a search on G-INFO but couldn’t find out which registration goes with it. Perhaps someone else can fill in the blanks.
