What Tiny Details Of Saturn V Rocket Actually Did

I've now got 2 Saturn V models and wanted to look at the detailed surface features which all have a real function as part of the design.
The word 'Greeble' isn't correct of course, it's a model building term that refers to all sorts of non-functional detailling added to plain surfaces to make them look more interesting.
