Vintage DECI LOG LOG Slide Rule, Pickett and Eckel Circa 1946-50
The rule is in good condition for a collectible. All of the graphics are in excellent condition. The middle sliding rule is very difficult to move. With effort it could be extracted, cleaned, and waxed to improve operation. The glass indicator moves freely.
Please see pictures for a close up look.
This 12-inch duplex slide rule is made from a magnesium alloy coated with white celluloid. It has a flat glass indicator with metal sides and stainless steel end posts. Both ends are engraved as follows: T.R. Flint.
This rule comes with a olive drab cloth sleeve which might indicate it was issued by the military. No way for me to know for sure.
