[Ads-l] Query on Coinage of "Radar"

[Shapiro, Fred]

This is the kind of question that military buffs on this list might enjoy researching.  The term "radar" has a first use of October 1941 (from the New York Times) in the Oxford English Dictionary.  I think I was the one who contributed that citation to OED.  Various sources I have looked at say that the acronym was coined by the U.S. Navy in 1940.  Can anyone point me to publications using this term before October 1941?  Classified uses that were later reprinted or cited to would also be of interest to me.
