1. The Gun's History
There are several points to make in conflict with the text of this marker. To start, the gun is not a smoothbore, but rather a rifled gun. It started life as a smoothbore, however. Cross matching the muzzle markings with secondary sources, this gun was originally cast as a 10-inch Rodman smoothbore gun. The gun was made by Fort Pitt Foundry, Pittsburgh, Pennsylvania in 1862, inspected by Jasper Myers. It weighed 14,905 pounds at that time. The gun's original registry number was 45.
The current muzzle markings read (from the 12 o'clock position, clockwise): "No. 34 - 15915 lbs - D.A.L. - B.I.W. - 1884." Translated this means the gun is registry number 34 weighing 15,915 when inspected by David Alexander Lyle, at Boston Iron Works (South Boston, Massachusetts), in 1884. The gun is one of approximately 30 which were modified from smoothbore to rifle by inserting steel sleeves through a hole cut
in the breech. Thus modified the gun became an 8-inch Rifled Rodman Seacoast gun.
Based on this administrative record, by way of the gun's markings, clearly the gun was NOT at Fort Morgan in 1861. Likely it did not see Confederate service. And logically then it was not recaptured by Federal forces in 1864. Clearly the gun was at Boston, Massachusetts in 1884 for the modification described above. But given the limited funding for military projects at that time, it is unlikely the Army would have retired the piece four years later. Several guns of this type served the nation's defenses until the Spanish-American War.

This gun, made by Armstrong-Whitworth & Co. in England, was sold to the American Army for service in France during World War I. It now serves as the American Veterans of Foreign Wars monument at the Customs House. The placement allows for easy comparison to the Duncan Cannon, showing the progressive developments in artillery technology after the Civil War.
