Ferro Enamel Corp

As with other small incendiary bombs, the M 4 was loaded and clustered not only under private contract, but at certain CWS arsenals as well. Rocky Mountain and Huntsville Arsenals loaded, clustered, and packed this bomb. No serious complication arose in filling the M74, but the Ml42 fuze caused a considerable amount of trouble. The design of this fuze, which was manufactured under private contract at the Ordnance Fire-lands Plant, Marion, Ohio, was such that visual observation did not reveal whether the fuze was armed. After several accidents caused by explosion of the fuze, the CWS changed contractors. The new contractor, the Ferro Enamel Corp., initiated a number of changes to improve safety and handling procedures, which resulted in satisfactory working conditions and a satisfactory fuze. ... 

The government owned plants were Firelands, San Bernadino, Turlock, Zanesville, Birmingham Smoke Mix, Birmingham Smoke Pot, Midland, Lake Ontario Ordnance, Niagara Falls, and Duck River. The CWS sponsored plants were operated by Lempco Products Co., Bell Aircraft Ordnance Division, Bell Madiine, Ferro Enamel Corp., and Rheem Manufacturing Co.
