This fine example of the Curtiss OX engine is fully restored and on display at the San Diego Aerospace Museum, California, along with another one which is fully chromed and inside a glass display case! Unfortunately, due to the high shine on the chrome and the glass it was not possible to get a clear picture because of the reflections; but what a sight! Magnificent!

This OX is in the Imperial War Museum, Duxford, England and affords a good all-round look at the details. Note the different black and silver colours.
