This medal's obverse bears worker about to strike snake on anvil with sledge hammer; mobile 8-inch army rifle on reinforced railroad car chassis in the background. Around, PRESENTED BY THE AMERICAN CAR AND FOUNDRY COMPANY; below, 1917-1918.
The reverse bears Columbia walking l. with palm frond; Statue of Liberty and sun in distance. On left, FOR SERVICE FAITHFULLY RENDERED; lower right, CB - JK.
The medal was presented to the company's employees for their faithful service during World War I. Accompanying the medal was a card containing the following message from William H. Woodlin, the President of the American Car and Foundry Company:
"The enclosed honor medal is awarded as an evidence of the appreciation by this Company of the work by you on its munition contracts, and as a lasting testimonial of the service rendered by you as an industrial soldier in the winning of the great war."
The signature CB - JK inidicates that the medal was a collaboration between Beach and Kilenyi (maybe design and sculpture) but I did not manage to find any evidence supporting the nature of their collaboration. Harry Waterson believes that Beach designed the medal and Kilenyi executed the bas-reliefs. His evidence is that there are design drawings and, according to him, "Beach could draw, Kilenyi couldn't."
This medal measures 63.5mm in diameter and was struck in bronze, silver, and 14k gold by the Gorham Manufacturing Company of Providence, RI. The silver variant is quite rare and the gold exceedingly rare but no mintages are reported.
According to a book about the company, a combined total of 7,500 pieces in all metals is believed to have been struck.
