I'll have a go purely off the top of my head. Don't know all of them but here goes... anything with an asterisk is a very rough guess.
From Top left..Mick Gale, Nicholls*, Hilton, Torney, Ryan*, Bowden, Bower, Prescott*, AK, ?, Rogers
Charles*, Bourke, Turner, Richo, The Donut, ?, Benny Gale, Holland, Gaspar, ?, Bully, James
Rombotis*, Plapp, Dunc, Cambo, Knights, Daffy, Powell*, Merenda
Harrison*, Moore, Brodders, Chaffey, ?, The Birdman, ?, ?,?, Proctor
I'm sure Tivendale is in there somewhere but I can't pick him.
A crap effort I know but could someone help me fill in the gaps or fix any that I got wrong?
