Maybe you're right, Mr C, I only have a vague memory of it, anyway. The 9 and 46 were definitely joint Accrington/Blackburn Corporation services - as was the 90 (Accy - Ossy - B'burn Hospitals). Incidentally, the bus in the picture is a Leyland PD2/1, one of a batch acquired by the Corporation in 1947 and disposed of in 1961.
Right, I'll get me anorak...
