Vintage Delft Kerosene/Oil outlet Lamp

This is a beautiful blue and white Delft kerosene lamp. It is hand-painted and marked at the bottom. The on switch is stamped made in France Gaudard. It is missing the glass cover. According outlet to the Delft code list, AG painted on the bottom is from the year 1911. Measures approximately 11 inches in height. I have no idea if this lamp works or not.
