To my knowledge, he never worked on JN-25. JN-25 began to be broken in the middle of 1942. There had been only the scantiest of results prior to the Japanese assail on Pearl Harbor. I have only the highest regard for Rochefort but, if he claims differently, he is wrong. Marc msmall@infionline.net FAX: +540/343-7315 Cha robh b?s fir gun ghr?s fir!
