Eddystone Arsenal

As orders from combatants exceeded the production capacity of Baldwin's Philadelphia factory, new manufacturing facilities were built in Eddystone, Pennsylvania.

[1] Baldwin received locomotive orders from Imperial Russia, France, and the United Kingdom of Great Britain and Ireland as those nations' manufacturing facilities were refocused on armaments production.

Baldwin's vice president Samuel M. Vauclain visited Russia in 1914 to obtain orders for thirty 0-6-6-0 Mallet locomotives for the 3 ft 6 in gauge railways between Arkhangelsk and Vologda.

Baldwin formed the Eddystone Ammunition Corporation on 10 June 1915 to manufacture 2,500,000 3-inch (76 mm) shrapnel shells of Russian design.

Contract changes resulted in most rifles being completed to the modified M1917 Enfield design, which was carried by nearly two-thirds of the American Expeditionary Forces.
