Although the leaflet issued at the time of the road layout changes at Market Place said that the B (as it was at the time) used Duke Street to get onto West Street, I suspect they always went along St. Domingo Street as shown here, since it would otherwise have been difficult to get across to the stop at the bottom of West Street. The early conversion to one-man meant that the B got the newest buses in the fleet, such as 5185 seen here, for the first time!
