That's a late (60's-80's) AustralianBren chest, they put those new type of fittings on their chests along with the bumper bar on both sides of it.
No, BP's chest does NOT have the 'Bumper Bar' or those types of catches. It has the 'Normal' flat hasp types with rotating loops for a padlocks. It is stenciled Bren, Machine Gun, DP. So I am assuming it held one of the DP Brens that came over from Aus in the original HUGE batch a few years ago. Thier brens had Yellow Bipods to denote Drill Purpose. It is a normal issue chest but with the words added later onto a coat of shiney deep bronze geen. Wartime coloured chests would be painted either Brown or green in a Matt colour. Still fitted out inside with ALL the fittings for the C.E.S, IE: Spare barrel, mag, brushes Etc, Etc. & all the felt padding complete.
Agh, yes thats the one, the fastners are similar to the Spares box, but not the same. I thought I may have had a few left but I must have sold them all, I've just got 2 of the normal fastner types left now. I seem to remember thinking it was a Aussie mod as 2 of them had the Liverpool NSW address on the side.
