Please refer here to Colin Owen Badges Nos.811 and 812.

This is the chrome variant of these collars which came out after 1963. They have Pin Fastenings.
"Quartermaster's Comment":-  Colin Owen logs them as Citizen Force Infantry......or Skiet Commandos.........We might say here "Home Guards".
They had a lot of fun in their time.......mostly farmers who must have done a lot of Shooting and Drinking over the weekends!!!!!
