The timber used is described in two different articles on different dates, but contradict each other. One states local timber with Kauri deck. The other, Oregon with Teak deck. There is a chance that they are refering to two different boats, but they are of the same launch date and place, and both for Customs.
In regards to the engine, the article refers to 'engines with cylinder diameter of 10"'. As there is only mention of one propeller, one assumes the writer is refering to each cylinder as an engine. This would tend to indicate the writer was not familiar with marine steam engines, and probably assumed a layout similar to railway locomotive
