Adelaide College uniform button
Note the very long loop shank. The button is quite convex, and the length of the shank had to be long for that reason; also to pass through thick coat material. Not a great design! I bet the shanks were often bent.
From the NSW Government Gazette, 20th November 1846 page 1458. I have not yet found a description of these. A colonial button to wish for!
The Sydney Foot Police were later merged with other forces into the NSW Police.
From the Albury Banner and Wodonga Express, 20th December 1895 page 30. Note that only the buttons, clips, and “one cap per annum” were supplied. The employees were expected to buy 2 three piece suits a year.
