These squat, muscular locomotives were built over a fifty-year period, with the later ones coming out in the Robert Stephenson & Hawthorns era.
Contractors, collieries and quarries all found a use for these strong and dependable engines. Two 3ft 6ins gauge examples were constructed for the export market.
The kit also includes alternative RSH-pattern buffers, chimneys, sandboxes and smokebox fronts, so most of the variations within the class can be represented. Full cab detail is included.
