I forgot to mention earlier, but Jon Goff has had good stuff lately.
Also, check out a nice picture of Titan 1 gimbals (you can click for a big picture but it’s quite a slow site). I’m pretty sure this is the first stage so there is actually another engine behind the one in the picture. The thrust mount and the gimbal link arms show quite nicely anyway. It’s remarkable how complex stuff turns anyway despite the simple principles and best intentions of the designers.
