Derham Body Company

To cope with the increased activity Derham required larger premises so a purpose-built plant was erected in Rosemont, Pennsylvania where many of their customers lived.

[2] Derham always made one-off custom bodies but they were financially stabilised by taking on regular series production work.

From early on dealers would order more than one body of a particular design and this cost-saving practice grew to become short production runs of perhaps 20 or more identical automobiles.

Most of their bodies were built in series on Packards and Hudsons but they continued to build one-off cars on any chassis their customer required.

Derham reprinted it listing some current and former clients: Raymond Loewy, Pope Pius XII, Cardinal Spellman, Duke of Windsor, Harry Truman, Cole Porter, Gary Cooper, Louis B Mayer, James Forrestal, Herbert Pulitzer, Lily Pons, Leopold Stokowski, Bernard Baruch, Rodman Wanamaker and Marjorie Merriweather Post Davies.
