And far as this particular model goes, There really aren't any pieces that stand out as being very uncommon anyways. It has a ton of common curved and round shaped pieces I've seen many times, and that's just because rockets tend to be cylindrical. Standout pieces are usually stickered/decal pieces.

I'd get it not just because I'm a space travel buff but because of the scale- it's a meter tall! Great job bringing out the immense size of the Saturn V, in Lego form.
