Sorry for being "picky", Gents, but the S2F (S2 after the redesignations) was (is) an early fifties plane, and saw fleet service until sometime in the late sixties or early seventies. Checking Wikipedia, they say it entered fleet service in 1954, and was retired in 1970. I fiddled around with a few of them in '61 and '62 when I was stationed at North Island at Overhaul and Repair Out Ferry Line.
