hello all I am happy to present this Succès lamp which was promise to the trash because of so much troubles. The swan neck was folded, near to fall down. It needed a sleeve and redo the curve. the burner was in very sad condition : no knob, and the brass was rotten, so many parts have broken while dismantling. As this burner is a little bit complicated, it was difficult to understand the functioning. It has been necessary to rebuilt some parts with the great help of a friend of mine. I know nothing about this model and burner. Power is around 150/200 CP, production year : 1920/25 ? by Guenet et Abbat, 13 et 15 rue du Pont aux Choux, Paris. When I took the pictures, it was running since 4 hours with only 500 Gr pressure.
