These were quite rare in the commercial world because when the L1A1 rifle energa launcher came on stream, the No4 ones were returned and the pouches retained for the 'new' L1A1 launcher. It suddenly dawned that the pouch for the energa launcher was on the side of the 58 pattern pouch so quartermasters were told to dispose of the pouches or return them to Ordnance. Due to there unsuitability for pretty any other application in the known universe, most, if not all, went straight into the bin!
