Aristo 622 Circular Slide Rule. Nearly New, in Original Packaging! This is a well-designed, practical, pocket slide rule. It has scales corresponding to C, D, CI, A, and K. The rule is in nearly new condition, practically unused.

The disc and cursor both turn very smoothly. The plastic carrying case is included, and is also nearly new. Also included are the German-language instructions, and the original inspection control slip.

Not something one sees every day. The original packaging -- a ziplock-type envelope -- is included. The outer ziploc is the only piece that shows significant wear -- some dings, a small tear, some spots of dirt, a pen mark, and sticker with the numeral 2. The paper instructions have a small, barely noticeable crease, but are otherwise in excellent condition. The metal pivot shows a small amount of tarnishing from age.

There are some tiny, barely visible scratches on the face of the moving disc, which were presumably there when it left the factory. With these exceptions, it would otherwise be hard to tell that this slide rule was less than brand-new. The rule has a blind stamp near 1.02 on the K scale, hard to photograph, that reads 2LS1. That presumably indicates that the rule was manufactured in Hamburg in 1973, in other words, this is a late model made shortly before slide rule manufacture was discontinued altogether. No purchaser has ever reported damage to a slide rule in transit.
