The early history of this loco is unknown; it was discovered at Hall & Co., Washington Pits, Sussex, and initially preserved by the Wey Valley Railway. To the Cadeby Light Railway 24/9/1982, and then moved to Apedale on 22/4/2006. This is the only known Class MM O&K. It is believed that the MM type was a design only sold in the UK. It seems likely that these locos were assembled in the UK by O&K’s UK agent, William Jones, using a kit of parts supplied from Germany.
