TTN, our No 1s were built with staybright flats in '61.
Aaron, I got my first clipon in '65 in the States. Game definitely when I saw the stn cdr at Waddo wearing one in '67.
Jindabyne, those M&S ones were also available, with epaulettes, in that awful blue-green in the late '60s too. Different shade from the NAAFI ones, now there's a surprise.
