In 1937, Western Electric and the Bell System introduced the 302, created by the renowned industrial designer, Henry Dreyfuss. The shell of the 302 was intended to be cast out of metal. However, in 1941, the critical war-time need for metal caused Western Electric to retool to make the 302 out of molded thermoplastic.
