Description

Aristo 908 TriLog Slide Rule. NEARLY NEW IN BOX.
Powerful, 22 Scales.   On the obverse are the scales LL1 LL2 LL3 DF // CF CIF CI C // D L K.  On the reverse are the scales T1 T2 A // B BI CI C // D P S ST.
Unlike most U.S.-made slide rules, the Aristo Studio includes the very useful Pythagorean P scale.  Other very useful, but less common features include a BI inverse squares scale, and both T1 and T2 tangent scales.  The Aristo 908 TriLog is a very powerful calculating instrument, useful for scientists and engineers.
The slide rule is in nearly new condition. The white-and-red plastic case is included, and it is also in new condition.  The original factory inspection slip is included, and is in new condition. The instructions have unfortunately been lost over the years. The outer box is in very good-to-excellent condition.  What appears to be the original price is written on one side of the box in pencil.  See photos.
Both slide and cursor move very smoothly.
Satisfaction guaranteed! You may return the slide rule for a full refund for any reason, or no reason at all, within fourteen days. Purchaser pays return shipping.
Shipped within three business days, usually sooner.
International bidders are welcome!  Any import duties are the purchaser's responsibility.  The description and price will be accurately listed on the customs declaration when the rule is shipped.
All slide rules we ship are very securely packaged.  Most packaging is recycled.  We have shipped slide rules all over the world.  No purchaser has ever reported damage to a slide rule in transit.
Please ask if there are any questions.
