Nice! Why have I never seen an aluminium slide rule?
Almost ALL Pickett Slide Rules are aluminium.
The only thing I dislike about those aluminum Picketts is that unless
properly maintained, they can oxidize like hell, rendering them
useless.
I used to sometimes see them at swapmeets; usually in the 'junk box',
corroded and in a very sorry state.
