Very rare Thorn Gamma Classic street lantern

In the early 2000's, Thorn's iconic Gamma 6 lantern was superseded by the "Gamma Basique", essentially a revision of the lantern. Alongside it, 3 decorative models were released: the Gamma Modern, Gamma Classic and Gamma Deco. These 3 models are incredibly rare nowadays and were never at all popular, for some reason. Here is a Classic variant photographed today in Chelsea, London.
