Made in 1914, one out of 15,037 of Navy contract 1911 might be one of the most difficult standard issue 1911 to acquire.
All these issued to the battleship like Arizona, Pennsylvania, Nevada and Oklahoma. Maybe it was at Pearl Harbor? Most of these US Navy model be destroyed during war time.
When I got it, it has a different grips installed. After couple month searching, got a pair of Colt 1915 original diamond grips from a 90 years old US Marine. Return it back to orignal, now I am happy man.
