I travelled on them many times when I was a kid, on the 74 and 75 route like in the photo, West Bromwich to Birmingham. The route was shared by West Bromwich Corporation and Birmingham (this is pre WMPTE). Once a year it was to see Father Christmas in Lewis's. They used to stop outside Snow Hill station and return via Constitution Hill. Years later, I reluctantly used the 74 or 75 to get to Rookery Road Handsworth to get on the no. 11 outer circle to Witton. This was only when my own transport had broken down which was often.
