Recordings of 78-RPM Morse Code training records

Recordings of 78-RPM Morse Code training records, prepared by the U.S. "Special Service Division, S.O.S., War Department". Manufactured by Allied Record Mfg Co., Hollywood, Calif. (See images of record labels.) There is no date on the recordings but judging by the content ("CORREGIDOR... Get the message through!...") the estimated year of manufacture is probably 1942 or 1943.

The recorded material consists of a code aptitude test, introduction to Morse Code letters and numbers, and training at various speeds up to 16 WPM. There were originally 22 records (44 sides) in the collection but the final one is missing here.

These re-recordings of the original phonograph records have been processed in order to remove some of the disc surface noise.
