Old USA Slide Rule (Beech)
- £15.00
An old wooden slide rule, 'Made in USA, Lawrence Engineering Service, Wabash Ind, Pat Pend'.
This rule has the nice feature of retaining its original carton.
I've just noticed there is a metal and glass/plastic sliding view finder inside the carton which isn't photographed which slides along the rule.
Length: 8"
Condition: all parts move freely, carton lid missing on one end, not 100% what wood it is made from, please see photos for condition.
