Overall view of an outboard H-1 engine. I believe that the blue holddown arm at left is at Pos. II, so this would be Engine 1.

The cover appears similar to the ones shown in MSFC-6864131, although this is the only place I recall actually seeing engine covers like this in person.

It's interesting that when the S-I-D stage was initially placed on display, it seemed to lack aspirators and heat exchangers, but that they seemed to have been added some time later. I don't know whether the entire engines were swapped out or the aspirators and heat exchangers were added via a field replacement kit.

Of course, it could just be that these engine covers were added for effect and were stuffed with old newspapers or something ...

Also note the insulation blanket protecting the engine opening at top.
