I've seen some so called "short holdalls" advertised on eBay as being a late L4 version holdall which is not intended to carry a spare barrel. It is advertised as only being intended to hold the wallet and cleaning rod and other associated bits apart from the spare barrel. I have never actually seen one of these so called late version "short holdalls" in the flesh. Is it correct that there was a late version holdall for the L4 Bren that didn't have provision for a spare barrel or is this item intended for another use?
