1. Converting a Cannon Marker
Inscription. Feel the grooves inside this rare cannon barrel. This Rodman cannon was cast in 1861 as a 10-inch smoothbore, which fired round cannonballs. To keep up with modern technology, the U.S. Army in 1884 inserted an 8-inch rifled sleeve into the old cast-iron barrel, because rifled guns had longer ranges than smoothbores. Steel later replaced cast iron, and the old guns were sold for scrap. The piece on the right is a smoothbore. The piece on the left is part of a rifled bore.
