Aristo 869 Pocket Studiolog Slide Rule. 27 Scales. Scarce! Nearly New
Aristo 869 Pocket Studiolog Slide Rule. The pocket-sized 869 is quite hard to find. The 869 carries an amazing amount of computational power for a practical, pocket-sized slide rule. The rule is in excellent condition.
Nearly new, with very minor scratches visible only on very close inspection. The original leather case is included, and is also in excellent condition. Slide and cursor both move very smoothly. The original quality inspection slip is still present.
The Studiolog is a powerful, end-of-an-era slide rule. The slide movement is very smooth. Perhaps it was a secret in the polymer composition. The movement of the slide is smooth-as-silk. Cursor moves smoothly as well.
The instructions originally packaged with this particular rule were unfortunately lost over the years. These instructions instead came from another source. A prior owner hand-bound the instructions in a unique Bristol board-type binding, and added some handwritten notes of his own. You may find these notes interesting in their own right.
No purchaser has ever reported damage to a slide rule in transit. Please ask if there are any questions.
