I know and understand that the cabane struts/wing centre section had bracing wires, in the Gauntlet AND Gladiator’s case running alongside the fuselage fore and aft, what I don’t think the Gauntlet had, and what the Gladiator most certainly DIDN’T have:
were the wires running athwartships from the fuselage centre line out to the top of each cabane strut. There is so much commonality in design from the Gauntlet to the Gladiator, and why wouldn’t there be, so I can’t see why the Gloster engineering team would change the bracing wire requirements unless there was a good structural design reason to do so.
