**Graphical Firing Table Slide Rule**

**WW II Vintage**

This slide rule was produced by K&E after 1943. There is a 1943 date on the rule. The scales are obviously for artillery calculations. There are three slides for different types of guns and different types of calculations. There is a C and D scale which qualifies the rule as a slide rule.

The rule is of the Mannheim type. The base of the rule is mahogany with a lighter wood used for the stators. The rule is 18 1/4 inches long and 2 3/4 inches wide. The scales are 15 3/4 inches long. The thickness of the rule is 5/8 inch. The surface of the wood is painted and the scales are screened on.

Scans are from the collection of Clark McCoy
