American
Airways Sikorsky S-38-C NC10V
(c/n 314-14)

So far as I can
ascertain, this was the only Sikorsky S-38 to be operated by American
Airways.
Its base of operations appeared to be
Chicago but I am not sure if it was used for passenger or
freight/air mail service. Steve
McEwan indicates (plausibly) that it was probably inherited from
the
Colonial Division for the Toronto route.
