Military Map Plotting & Calculation
This lot features a military map plotting parallel rule and a Thornton duplex slide rule. These tools were essential for accurate map reading, navigation, and calculations in the field. The parallel rule allows for transferring angles and distances on a map, while the slide rule facilitates complex calculations without the need for electronic devices. These items represent a piece of historical surveying and navigational technology.
Condition & Collectibility
The condition of these tools appears consistent with age and use. There are signs of wear and possible patina, which is typical for vintage military equipment. These items would be of interest to collectors of military memorabilia, surveying instruments, or vintage calculating devices. They also hold appeal for those interested in historical navigation and map reading techniques.
