Nice!  Why have I never seen an aluminium slide rule? 

Almost ALL Pickett Slide Rules are aluminium.

Wow!  On a 7 foot rule you should be able to get four sig. figs without
too much interpolation anywhere along the length.  Or are the markings
too coarse for that? 

The 7' rule is simply a blown up version of a 12" rule.  Everything 7 times
bigger.  Sure, you can estimate a bit better, but you wouldn't really want
to try to calculate with this thing.  Its massive!!

PS: Brand new Pickett ES500 rules (quite nice model) can be had for US$25 at
the Gemmary.
Tell them I sent you ;)
