Gauge for Priming Tubes 1860

This brass "Gauge for Priming Tubes" from 1860, created by the Marine Stoomvaartdienst, was likely used to measure the size of tubes used in priming devices for cannons or other weaponry. The object features two gauges, one with a screw-on top and the other with a smooth, domed top. The inscription "n°3" is visible on both gauges, signifying its specific size and purpose. This type of object is a testament to the precision and technical advancements in maritime and military engineering during the 19th century.
