Part 2 of Steve Ginter's series on the S2F and its variants is now available:
It was written by Doug Siegfried and Steve Ginter. (Bob Kowalski and I wrote Part 1. See http://thanlont.blogspot.com/2016/01/grumman-s2fs-2-tracker-monograph.html)
In 249 pages, Part 2 provides a summary history, heavily illustrated, of U.S military squadrons when they operated the S2F/S-2 and the WF-2/E-1B. That includes Marines, reserves, test, training, stations, etc. You can buy it directly from Steve here: http://www.ginterbooks.com/NAVAL/NF102.htm
