After many years of research and a number of new discoveries, we have sufficient detail for Chris to create to his exquisite models of the locomotives, carriages and wagons. Many of the items of London & Birmingham rolling stock are well known due to drawings in contemporary publications. However care needs to be taken not to confuse the initial plan drawings, known as specification drawings, such as those in Peter Lecount's book, more on this later. Those in Brees are also most likely copied from the specification drawings initially produced by Joseph Wright with Nathaniel Worsdell and possibly Thomas Clarke Worsdell (II). None of these drawings however are without the problem of interpretation, particularly when producing a 3D scale model. Chris is doing an amazing job to bring these models and history to life, I'm sure you will agree.
