The following illustrations were created by James Poynor utilizing the 3D CAD program SolidWorks. Mr. Poynor worked from the original BuOrd blueprints to make a drawing for each of the individual components of the guns. These were then combined to make the illustrations shown below. These illustrations are quite large and can be zoomed in to show very small details such as the breech face engravings and ID plate lettering.
Mr. Poynor is working on additional items and this page will be updated as those are completed.
