Circa 1905-07 - Tin construction with litho cab and roof. Tin front wheels. The one pictured above is unique in that the cylinders are lithographed in the same blue / white stripe as the roof. See similar No. 2

The example above has the black boiler, while the one below is a brighter blue.

Different lithographs used on roofs for small tin locos - the one below is upside down, giving the top a 'gold look'
