We did a posting on our old site Bookride on Chick Marrs Quinn's unfindable book The Aluminium Trail a self published and much wanted book about US aerial operations in the Pacific Area in WW2  The book is dedicated to 1st Lt. Loyal Stuart Marrs, Jr., Chick's husband who was killed February 27, 1945.  The 'aluminum trail' title refers to the pattern of air crashes in the difficult Indo-China regions, especially the Himalayas. People who lost relations and loved ones flying so far from home eagerly want this rare book and not a few libraries. Amazon sometimes has it at bearable prices.  As for Aluminum (or Aluminium as it is known in Britain) Everybody's Book of Facts (1940s) reveals this:

 The youngest child of the great family of metals is aluminium, which 50 years ago was as expensive as silver, just as silver was once more precious than gold, and iron more valuable than either. The first to isolate it was the German chemist Friedrich Wohler in 1827. Napoleon the Third used an aluminium spoon at state banquets, and had a set of buttons for his uniform of the same substance. It then cost about £109 a pound. In 1880 only 70 pounds were produced annually; in 1885 13 tons; in 1926 some 200,000 tons; now even cooking vessels are made of aluminium.

The metal is never found by itself but always in combination with other elements, including clay. The United Staes is the chief producer, although it is believed that aluminium worth about £288 million is available in the Gold Coast colony. The largest night sign in the world is made of this metal. It  graces the RCA building in Rockefeller Centre, New York, is 24 feet high and outlined in  neon lighting.
