The loco was ordered in 1908 by Howe's Plaster Works, to work between the private sidings (Howes Sidings Box) on the Settle & Carlisle near Cumwhinton, in Cumberland (as it was then), and their works at Cocklakes. This private branch contained quite a severe gradient up to the works - of which little trace is left today. Howes Plaster Works later became "Carlisle Plaster Co" (remember Carlite Plaster?) - and later part of British Gypsum.

In the early 1970's Steamtown in Carnforth were looking to obtain some smaller locos that were more econmical to use than main line machines, to operate their footplate rides.

The loco was purchased along with a number of sister locos, and was taken to Steamtown, Carnforth for preservation. They had been stored in a shed for a number of years, and it is recalled how thick the white Gypsum dust covering the engines was before they left

Upon arrival at Carnforth, the loco received attention to the boiler, and was painted in Campbeltown & Machrihanish North British livery.

The holes below the existing buffers previously house a set of secondary buffers that would match up with the small wooden wagons that were used in Cocklakes.

The loco ran at Carnforth for a number of years, and has recently been re-restored - and can now be seen operating at Riversway. The loco's first passenger run being on 13th May 2006.
