New uniform button from Carol:
??Commonwealth Shipowners Association by O’Neill & Co.
On the 10th July 2018 post Cam Smith shared an O’Neill Button from a shipping line. This button also has the typical ‘rope’ edge of naval and shipping uniform buttons.
The Commonwealth Ship owners Association was formed in 1905 by Howard Smith Ltd, Adelaide Steamship Co, AVSN Co. Ltd., Huddart, Parker & Co, McIlwraith, Mc Eucharn & Co. By 1946 many shipping firms in Australia belonged to the organisation to manage freight costs, fares, and allocation of business. In 1946 it extended into stevedoring.
This is only a guess … any other ideas where this button originates from?
