The limited company was formed in 1975 at Cote, Bampton, Oxfordshire, continuing what Alan Keef had already been doing for some years as an individual.
In 2008 the company built the frames, running gear and mechanical parts for two Parry People Mover railcars for use on the Stourbridge Town branch (139001 and 139002).
In addition to the replicas for Beamish, the company has also helped restore a number of historically significant engines including both UK preserved Baldwin Class 10-12-D locomotives – No.
However, this project was eventually paused and the WHHR moved the locomotive to the Vale of Rheidol's Aberystwyth workshops for completion in 2020.
