How many ex-National Bus Company (NBC) names or independent ex-NBC operators left?

[BVW]

Not exactly a classic NBC name, but when Eastern Counties were split back in 1984 the coaching activities were hived off to Ambassador Travel who still trade out of Great Yarmouth.

London Country (South West) - could be used for Arriva buses in the Guildford area, accepting that a lot of these routes were formerly Alder Valley and before that, Aldershot and District.

You could go a bit further - Arriva has pretty much all of what was London Country now.

Stagecoach still has the post 1985 United Counties area and Arriva has both the Luton & District and Milton Keynes Citybus areas (which were separated from United Counties after 1985).
