#4 charger guide attachment welded VS pinned

[Peter Laidler]

Here it is from the horses mouth. Nothing to do with weak bodies. They were all MANUFACTURED by being pinned in place. Early on, they were screwed in place with two 'taper-lock' screws. During the 'in inspection' process at Field and Base workshop, you'd lever a screwdriver under the bridge and if you saw an oil squeeze or felt any looseness, you'd drill a small countersink along the base line on both sides and fill the countersink with weld. Simply as a means of retaining it for good.
