I have just learned from Peter Nicholson that this is a bogus profile!. I had received information several years ago that the plane at the National Naval Aviation Museum's O-1 was actually 51-11986 marked as 5L14981 and so made this profile when I originally posted this photo circa 2006.
Since this has been verified as the actual 5L14981, I have moved my photo, but there are two photos left on this profile which should be moved, and then the profile deleted.
