The origins of this carnival float are not known, but it appears to have been fabricated by the Railway Company in house for use during the annual carnival procession along the promenades at Douglas at some point in the 1930s, prior to which a decorated Road Services omnibus was entered in the parade bedecked with floral decorations.

Modelled on No.16 Mannin and with a broadly similar outline to its counterpart, it is believed to have initially carried the then-standard holly green livery and was fitted with a number of original components, notably spare Ross “pop”  valves and one of the steel domes painted to simulate brass, and painted-on “Mannin” nameplates.

As built the dummy wheels and rods were connected and the outline was mounted on the frames of a road vehicle, being self-propelled with moving rods; latterly it was mounted on a frame and towed along by a tractor.  It is believed that it last entered the procession in August of 1977, by which time it was wearing the spring green livery.

Stored between appearances in the old carriage shed at Douglas Station, it was believed to have been destroyed during a clear out around the time that the railway was nationalised in 1978 but rumours persist that it may survive in the north of the island.
