Thanks for posting. The new Army Museum at Ft. Belvoir is the eventual destination for the many deteriorating bronze trophy cannon at nearby Ft. McNair, according to my Army Museums contact. While the present conservation was do doubt undertaken by the Base Commander at Belvoir, not within the museum system, the museum folks aren't far away and will get to see the results. We've heard that the Army plans to put the bronze cannons from Ft. McNair under cover, which will of course stop the acid-rain corrosion that's been eatng them up as they sit exposed outdoors.
