The Mk1 and Mk1* Bren Barrel (by Peter Laidler)

[Peter Laidler]

Ah, yes Mk7. The 'earlier' barrel is in fact not a Bren but a ZB30 on trial. There are several identifying features but the principal one is the angled sight aperture of the backsight. All Brens had an UPRIGHT aperture that was in line with the rear of the body.

As for the barrel..., yes. See the straight taper flash eliminator and the gas vent holes. These holes were deliberately designed to allow the carbon fuelled gas (not strictly correct...) to vent. But Enfield knew better and produced the deep, stepped taper flash eliminator. See the next photo. This caused rings/ridges of carbon and ........ anyway!

The lower photo was taken at Burtphore Barracks in Tidworth according to the rear of the photo in our small library
