Below is the second earliest W class drawing in the Museum’s drawing collection, R996, dated 26 January 1923. This better represents the W class body than does R995, although over the next few years there were 14 changes to this drawing, mainly around the trolley pole location and the size of its base, as well as documenting the evolution of the body from one with roof ventilators to a ventilated roof. Drawing from the collection of the Melbourne Tram Museum.
