This image is titled "Old Cast-Iron Gun Carriage, Formerly Used to Mark the Field." The location is unknown. The 1895 commission report states: "The volunteer batteries of the Union Army on the grounds of the Memorial Association are generally represented by one gun and mounted upon inferior carriages. This commission resolved to substitute an improved iron gun carriage. Sixty-two new carriages have been contracted for. Of these about 36 have been furnished by the contractor and placed on the field and mounted with the kind of gun used by each battery, respectively in the battle. The others will be put in position as soon as supplied by the contractor. Excellent granite foundation stones support each carriage. The following have already been placed on the Union lines, viz:...Six carriages and 3-inch rifles (Rickett's Battery), on East Cemetery Hill. Three carriages and Napoleon guns (Stewart's Battery), on East Cemetery Hill. Three carriages and 3-inch rifles (right of Rickett's Battery), on East Cemetery Hill. Three carriages and 3-inch rifles (Wiedrich's New York Battery), on East Cemetery Hill. All of these guns on East Cemetery Hill occupy redoubts used by said batteries in the battle." (page 22).
