Vintage slide rule chart calculator to show how much wire you should route through conduit.
By Perrygraf, I am sure some things have changed since 1964, but it might still be usable as a general size function, vintage.

Fair to less than fair condition, but not poor. It looks much cleaner in person, the areas you see are scuffs and not darkened spots.
