The first of the 1963 c420 order wearing the 1960s version of the traditional PV&T white + Big Sky Blue (the color capture isn’t quite bsb, but is close enough for this image) paint scheme. (The earlier version of the white+blue scheme put the PARSONS VALE onto the white band, but the failed blue dip paint scheme had white text on blue, which was kept after that scheme was abandoned.)
