[1] Smyth Bros. owned around 1900 a logging operation using a steam tramway at Kennedy's Bay on the north-east coast of the Coromandel Peninsula, a few miles north of Mercury Bay.

[4] It had originally been ordered by civil engineer James Stewart to be used on the Waiorongomai or Piako County Tramway, but the deal fell through.

Smyth Brothers tendered subsequently successfully for the locomotive and used it from 1897 to 1908 at Kennedy Bay, before it was sold in 1908 to the governmental Public Works Department as PWD # 511 for railway construction at Picton and Otira, and finally scrapped in 1917.

[2] In 1904, Smyth Bros. found gold in one of their driving streams, Omoho Creek, exposed by the action of the floating kauri logs about 4 miles north of the Royal Oak Mine.

Strong gold was visible in the stone for over 30 feet (9.1 m), the size of the reef being up to 6 inches (15 cm) in thickness, so that an experienced prospector was contracted to retrieve the gold.
