That is a fantastic photo of the pigs being driven down Deritend - from the tram rails but no wires, it must date between 1885 and 1907. Thank you John.
I'm just doing somje work on John Hanson's map of 1778 which shows the beast market at that time in Dale End, north side, and the swine market in New Street, south side, just west of Worcester Street. That was over a hundred years before John's photo of course, but it shows a bit about the fascinating way Brum grew.
