Picture taken standing under the forward end of the F-1, showing the thrust
chamber, turbine exhaust manifold, nozzle extension, and the bracket supporting
the aft end of the engine as it is displayed.
Note between the top two hatbands where the tubes comprising the thrust chamber
become bifurcated (split in two).
Also note the rectangular tabs with studs welded to the hatbands on the engine
proper; these would support the thermal insulation which is installed on the
engine for launch or static test.
