Mum and Dad found me another phone box in rural Scotland last week.
(Coordinates 55°67’01.6″N, 3°60’79.6″W.)
Some interesting stuff going on with the paintwork here. The red exterior looks sad and neglected (common for rural boxes) but the frames round the glass panels have been painted white at some point (over a decade ago, judging by Google Street View). I don’t think I’ve seen one like that before!
