This Ordnance Survey map shows Brislington as it was some time before 1929. Ordnance survey maps can be a bit confusing because they didn't update everything all at once, for example this map shows changes to the railways up until 1927.
This is from map 111 "Bath, Bristol and District" in the Popular Edition (often referred to as the 4th Edition of Ordnance Survey maps, at the scale of one inch to the mile (1:63360).
