I think he is talking of the houses off pickup street. As I grew up there I was told that the boundary is a stream that runs under Spring hill road/moscow mill half way along a block of terrace houses, the street numbers actually change half way down the block so you have some that are Moscow Mill Street and some that are Spring Hill road(My Citizen paper round included SHR but not MMS and the people in the few MMS houses used to winge that I didn't post them a paper as they didn't get one as part of MMS, if I had any spare I'd shove one through for them as I'm nice like that
) . When they built the houses the stream was I believe buried in a pipe to emerge somewhere down near Newark street so technically some of the houses are Accy and some Ossy.
