Daum crystal lamp France free-form base

Here is a very beautiful small lamp with a crystal base, very elegant, in a free form. The base bears the signature "Daum France" with the Lorraine cross between these two words. The Daum brand is also visible on the electrical socket, which leads me to believe that the whole piece is completely original. The free form is a style adopted by Daum in 1940 alongside the exclusive work with crystal, whereas originally, in 1878, it was a glassworks created by Jean Daum in Nancy. The design of the signature indicates that this piece dates from between 1945 and 1975 and is a first-rate piece. The bayonet bulb socket is made of silver-grey metal and has a screw-on washer to hold a lampshade. I have tested it, and it works perfectly. The whole piece is in good condition, with old electrification but entirely functional, crystal very transparent with just a small chip on the edge of the base. This lamp measures 16.5 cm in height including the socket, the base measures approximately 7.5 cm in maximum length and 5 cm in maximum width. The cable measures 160 cm in length.
