Data from "Narrow Gauge Tank Locomotive," The Locomotive Magazine, Vol IX (3 October 1903), p. 197.
The author doesn't tell us which 3-ft gauge line needed this locomotive. Locobase suspects it was a catalogue engine. Its tiny wheelbase lurked under a much longer frame. A very short capped stack, no dome to speak of (more of a manhole), side tanks spanning the length from front coupled axle to footplate, outside cylinders driving on the rear axle -- these were some of the noticeable feature.
NB: The direct heating surface (including the firebox heating surface) is an estimate calculated by subtracting the calculated tube heating surface from the reported total evaporative heating surface.
