Those huge BFA's were "standard" in Oz and, by extension, NZicon.

They were originally painted a bright yellow and later painted "signal red", after some "policy changes".

Regardless of the original colour, at the end of any training that involved the gratuitous consumption of blank ammo, they were all BLACK.

They were also a lot less likely to "go down-range" than the cheesy early pattern ones that consisted of a long bore plug and a riveted-on springy plate that engaged the sword bar / bayonet lug. These seem to be identical to the first pattern devices for the Canadianicon C-1.

Anyone got any advances?
