Note 1: CDSG Gun Card Collection from NARA - The original order to scrap the guns and carriages came on 22 Jul 1919. Gun & Carriage cards indicate that the carriages were recorded as scrapped on 6 Sep 1921 and the guns were salvaged on the same date but later entries indicate that the guns were both retained on 23 Dec 1922 as "ornaments", location unspecified.
