Potters Bar falls outside the TfL area (although there is some
cross over in the TfL funded routes also operate within Potters
Bar), so it's up to Hertfordshire County Council what the routes
are called.

Not when the PB1 first started, surely?

You live and learn. Apparently the PB1 was started in 1977 by
Dial-a-Ride; although a different website says PB1 was based on the 284
bus route at that time. Anyone know any more? I wasn't born and only
lived in Potters Bar 1987 to 2000

Just looked on busmap.org and the 284 appears in the 1970 map (doing a
loop around Mutton Lane, Darkes Lane and the High Street) but not the
1958 map.
