1942 Alclad Marking Documentation: “How to Do Aircraft Sheetmetal Work”

Another example of documentation of ALCLAD aluminum markings are provided in the 1942 publication How to Do Aircraft Sheetmetal Work, Carl Norcross and James D. Quinn, McGraw-Hill Book Co., Inc., 1942. (http://catalog.hathitrust.org/Record/001039989)

The entire text is not currently available online, but Google Books allows viewing of snippets of the work including the following from page 50: “Alclad is used to a great extent on all-metal airplanes. Usually the sheets forming the fuselage and the wings are of Alclad. Sheets are easily identified because they are stamped “ALC” preceding the identification of the metal, for example, ALC24S-T.”
