The 185 definitely serves Blue Bell Hill Village, its either a request stop in the late evening or served anyway and there is 185 starting at Kits Coty serving Blue Bell Hilll Village.Also you seemed to have missed route Nu-Venture route 192, and I may be wrong but I'm sure the 185 doesn't extend to Bluebell Hill Village
EDIT: Woops, living in the past, seems the 192 no longer exists - a symptom of looking at all the old timetables :P
The 185 timetable on Nu Venture's website doesn't actually show any midday 185 services which is odd, using other sources like bustimes.org and traveline.info shows the full 185 timetable and I'm certain the 185 serves both Kits Coty and Blue Bell Hill Village even if it's only occasionally and or a request.
