Holy $DEITY!
This is some site. Pure, hardcore, slide rule porn ;-). They even have all the slide rule models I own. Unfortunately they obviously sell rules to collectors, with appropriate [collector] prices.
Now I have to make my own circular slide rule, just to satisfy my craving. There is no way I could spend $250 of my fun budget on a really nice circular slide rule. You could buy a couple of refurbished e-ink readers for that price! So I will have to write some scripts in AutoLISP to draw nice circular logarithmic scale for me in AutoCAD. By the way, AutoLISP uses Reverse Polish Notation as its basic syntax. And *lots* or parenthesis.

By the way, why are all the "western" slide rule scales labeled by illogical and cryptic markings like C, D, A, B, S, S-T, instead of x, x, x^2, x^2, sin(x) that every technician out there would recognize without referring to the manual?
