SANDISON

The 'Sandison' brand was introduced in NZ in around 1933 and lasted until around 1935.

'Sandison' branded equipment was manufactured by K. S. Irvine, they were distributed by Epsom Brothers Ltd. Currently there are 3 documented models.

Made by Keith Sandison Irvine who later became the factory manager at Radio Corp, and who developed the (in)famous spiral dial for them.  He sadly died of a medical issue in hospital in 1939.

Models seem to appear in 1933, and then advertising stops - but the only sighted model appears to be 1935 (or late 34) as it uses a Radio Corp style aero dial and closely resembled their model 108 in design and layout.

Advertised by R. B. Fowler, Radio Dealers (who also sold Atwater Kent and later Zenith & Mullard) and Epsom Bros - both in Wellington.
