Jeez! Frank, those photos brought back memories for me! of course as techies we didn't enjoy touching all that ARMY hardware! The only bit of kit missing in them is the frame we used to line up the guns and rockets onto once they were fitted. Also I seem to remember we had lots of problems with the rounds jamming as they had to traverse 180 degrees to get into the breech of the GPMGs I know we loosed off quite a few rounds into the Butts, after jacking the aircraft into it's normal flight attitude..
