Art Deco Ziggurat Ceiling Pendant, Chromed metal and Opaline shade Finland 1930s

A minimalist Art Deco Finnish lamp with a ziggurat style opaline glass shade. The lamp is not stamped and hence a bit difficult to confirm, but many leading Finnish companies have produced such lamps like Taito, Idman and Orno. Many Taito catalogues from the 1930s have this under model no. 1612. Orno 1930s catalogues also has it. 

The shade is in perfect condition, but the upper part has some wear and really small bent in the metal that are consistent with it's age of around 90 years.
