Old Early Wooden Slide Rule (Boxwood) furniture Has two blades both markedAn old rare wooden sliding rule (Boxwood). We believe this rule is an early rule. The rule is marked with many different measurement markings including the brass slide rule being marked with measurements. If looking at the rule with the brass slide rule at the top, the lower edge of the bottom arm is bevelled. This same arm also is marked with a logo, at first glance it looks like the Moore and Wright logo however I don't believe it is as the logo
