Produced by Tecno SpA based on a Norman Foster project The two extendable parts can be moved with a manually operated cylinder mechanism with an eccentric device for the safe and easy positioning at the level of the upper main glass This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
