The Bronze 18pdr from 1632

Several years ago, Nico Brinck, the Dutch 17th Century gun expert and marine archaeologist (and sea captain) sent me several of his drawings. One drawing shows a bronze 18pdr manufactured in 1632 for the "Admiraliteit van West-Frislant", as the inscription says. The gun has a weight marking of 3480 lbs. The inside bore measures 13.8cm (5.433 inches). The gun has a length of 265cm from the ring at the rear of the barrel (with a 23cm part extending back) to the muzzle. That makes the gun 104-1/3 inches or 8ft-8-1/3in in English feet. The length in Amsterdam feet is 9ft-4in.
