Original canvas assault vest for issue to U.S. troops during offensives, going over the top , across ‘no-mans’ land and into meandering enemy trenches where grenades were the best tool at the GI’s disposal. These vests were made during the end of the war and also issued to troops heading to Siberia and the Archangel expedition in 1919. Most have manufacturer information stamped on the back. Holds 11 fragmentation or gas grenades. These appear to be unissued. Very limited.
