I am old enough to remember getting on one of these. used to get it from Upton Village either to go Moreton Shore or Birkenhead.
On display at Llangollen Railway station yesterday. A crosville bus also their but my lad didn't photograph that one (silly me left xd card out of camera doh!)
Seem to remember the crosville bus fares were a bit dearer than the blue buses but they were warmer and a bit plusher inside.

Oh yes, such memories , the 71A and 72 through Irby village!
