LSC571 is a PRV bodied (Body No. B37244) AEC Monocoach destined for Scottish Motor Traction (Scottish Omnibuses) fleet number B430. Built August 1954 this was the sixth of this AEC/PRV integral design.
Ian McLellan-Smith advises that, appearance-wise, the bodies for the Monocoach and the AEC Reliance were all but identical. The only clue to their construction being different was the fuel filler position; the Monocoach one going right through the lower moulding line.
