After 24 hours, you beat me to it by seconds Bogins
I don't think there is any doubt Voldy has cracked it.
There is a lamppost right by the stop sign, and the wooden hoardings continue some distance beyond the next lamppost down. Possibly beyond the third lamppost. They must be a minimum of 50 yards long, probably more.
In these two photos, you can see that the modern Grovesenor House block (between Cambridge Street and Charter Square), is slightly set back, (wider pavement). In the Moor 1977 photo, you can just see the upper floors concrete "filigrees windows" poking out beyond the older buildings (between Charles Street and Cambridge Street). The "foreshortening" is quite startling.
The old Barrel Inn? That's a new one on me!
