Dear Editor:   I am researching material for a novel I am writing about destroyers in the Pacific during World War II.  I am interested in hearing from men who have experience in Gunnery, Fire Control, Radio, Radar, and Main Engine; especially in the Benson class DD. I would also like to hear from bridge watch-standers. I would also like to hear from anyone who has knowledge of the composition and configuration of the ships in a Task Unit as well as a Task Group from 1942 to 1945.   Sincerely,.   John L. Alford 1500 SW 11th Avenue  #1601 Portland, OR  97201 (503) 241-7153 jlalford629@comcast.net
