Maybe the journal article needs another review😃.
Found this aerial image, Railway Club & environs, possibly 1940s (The highway had not been constructed).
All Saints is visible on the right foreground. Old PCs office is left of the C shaped building.

A different one, slightly earlier - Key indicates No 77 as ASC, RGC had also been established while 72 is the DCs office, 76 is the forest Department, 87 St Stephens church (moved to Jogoo Rd,) while 93 is the Railway European Club.
