NB1 AEC Regent III / Northern Coachbuilders
NB3 Guy Arab / Northern Coachbuilders

Northern Coachbuilders, not to be confused with Northern Counties, was formed in Newcastle-upon-Tyne in 1931.

They produced a standard post-war double deck body from 1946 until 1951, which was of composite construction and flexible enough to be fitted on several different makes of chassis including AEC, Leyland, Guy and Daimler. This body type was also available, in kit form, produced as a trolleybus and issued, by Little Bus Company, in 2004.

The kit is a re-master of a previous model from some years ago, and is again based on the AEC Regent III (NB1) and Guy Arab (NB3) chassis'. With the present kit design, the cab and bonnet line is easier to change, which represents the main differences between the various manufacturers.
