Honorable gesture on behalf of the person offering to repaint the guns...
However the article itself is rather poorly written... bounces about from various scrambled bits of data that doesn't flow well for a story.... parts that are fragmented, misleading and or confusing,.... "cannons were molded in Chattanooga, Tennessee",.... "carriages were cast within sight of three principal battlefields".... I think he was trying to say that the reproduction metal static display carriages were made in Tenn... but the verbiage he used was twisted up, unclear, missing vital details, and doesn't make much sense.. "Barrels were cast in Boston for the United States Department of Defense in 1847".... Um... Department of Defense didn't exist in 1847.... We had the War Dept. at that time in history... ""I was surprised to find out they were Confederate cannons and more than likely fired on Union troops,"... Normally we don't refer to something as being labeled as Confederate Guns unless they were made for and by Confederate sources... Something being simply obtained and utilized by Confederates at one time or another is usually deemed something different... Just wish such journalist would at least consult with a knowledgeable historian on any such matters before placing an article to print...
