Have you tried Sphere Research in Canada? They currently list New-in-Box (actually new-in-bag) Pickett N500ES rules in aluminium from C$69 (I bought two a little while ago). They sometimes have NIB K+E rules as well.

I have no connection with them other than as a customer. Prices are not cheap but new slide rules are not exactly common.
