DESNY modernist glass and metal lamp

Hard to find modernist 1930 amber colored glass and nickel plated brass by La Maison Desny.
There are many versions of this lamp in clear, amber, blue glass... with metal basis or with mirror basis. This one is very elegant and the color uncommon. A similar one auctioned at Sothebys Paris in 2007 for 3000euros. Please see pictures.
Glass parts are always shown in staggered rows, but I am not sure this is the original intention of Desny. On my pictures I propose another solution where glass parts are in alignment.
