This locomotive was built by Andrew Barclay in Kilmarnock and imported into New Zealand by William Brownlee for use in his Havelock sawmills in the Pelorus Valley and dispatched in 1892 to Brownlee & Co. William Brownlee had emigrated to New Zealand from Scotland in 1863 with plans to set up his own sawmills.
Unlike two locomotives previously supplied by Andrew Barclay this locomotive was built with a cab and a later style of saddle tank. It was also supplied with a log hauler which was driven by coupling rods which could temporarily attached to the rear wheels of the locomotive. Steam powered log haulers were not uncommon in New Zealand but were usually equipped with their own boiler. The arrangement with this locomotive saved the need for the additional boiler but required the locomotive to be lifted off the track to operate and was found to be less than ideal. As a result the log hauler was not used much.
The mill at Havelock closed in 1917 and in the following year the locomotive moved to the Lake Brunner Sawmilling Co at Ruru which was an associate company of Brownlee. It was here that the front pony truck was removed making the locomotive a 0-4-2ST. The locomotive was fitted with a new boiler fabricated by the Despatch Foundry of Greymouth in 1922.
The locomotive has been modified a number of times during its working life. In 1941 whilst at Lake Brunner Sawmilling it was fitted with the boiler, saddle tank and cab from a locomotive built by Shanks in 1875. (Shanks were established in 1840 to manufacture steam engines, iron bridges and steam cranes and was based in Arbroath in Scotland.) The wheel arrangement of the locomotives was changed from 0-4-0 to 2-4-2 and then 0-4-2. This was because the short wheelbase of the 0-4-0ST arrangement was unsuitable for working on lightly laid tramways. The frame was extended two feet at the front and rear to accommodate the pony trucks to carry the additional wheels.
At some stage (thought to be at Havelock) the locomotive acquired the nickname Aunt Sally.
The locomotive is now on static display at Havelock where it has been since 1967. The Museum at Haverlock, which is largely centred on the sawmilling industry, was established in 1973.
Since the locomotive has been outside at the Museum it has deteriorated and has had replacement flooring, additional outside steps, patches, and a welded-on cover for the water tank. These alterations have been made to enable the engine to be climbed on in safety by children. The locomotive is re-painted black at regular intervals.
