I recognised it right away, Paul. Even without the TGWU headquarters :-)

Did the 57 go round Swinton and come back though Pendlebuty or was that the 77? One did that and the other went though Pendlebury and came back though Swinton. Either way, they passed my Grandparents place on Bolton Road. They became the 56 and 57 before they were stopped altogether and one of them went to Belle Vue where I used to watch the speedway and I usually missed the last one back :-(
