There was indeed some 289 produced for the USN and Marine Corps and some were still serving at the beginning of World War II. The aircraft appeared in many guises some with cowled engines and some with enclosed hoods. They went from being straight forward observation planes to armed scouts and as such they were sold to many air arms across the world.

I believe this was the plane that shot the original King Kong off the Empire State Building.

This airplane is featured in the movie Devil Dogs of the Air (1935). My earliest memory (I was three) is of seeing one of these catch a wing while stunting over Subic Bay (no one was injured), again in '35. Cockpit photos in contemporary aviation magazines were available on microfilm at the New York Public Library in 1990, when I was researching it against the Cleveland model plans.

I can furnish a few b & w photos of this aircraft with squadron personnel, ca. 1930.

My father, then Lt. W. K. Berner USN, flew an O2U-3 with Scouting Squadron VS-8A in the late 1920s and early '30s (Asiatic Fleet). I have three photos of that squadron.

Thanks Steve

This aircraft served the USN and USMC in Nicaragua in the late 1920's. See George B. Clark's book "WITH THE OLD CORPS IN NICARAGUA". Some excellent stories about the flyers of these aircraft and their exploits during those campaigns.
