One of the most persistant mysteries on the Saturn V is the Foil-Batt insulation on the F-1 engines. It is mentioned briefly in the Saturn V News Reference and no where else I have been able to find.
Here's a few closeup scans I've made from launch photos. The insulation covers the engine nozzle and extension, and wraps around the rest of the engine components above them. The diagram was modified from a John Pursley drawing and shows the major shapes of the covers. Several of the F-1's on display around the country have the insulation attachment brackets on them in a pattern matching the shapes shown in the drawing.
Anyone having info/diagrams/photos of these please let me know!

Video Captures from "The Space Movie"
These captures show some good details of the insulation, but still no good overall views.
