This model of the Innocenti Factory is on display at Vittorio Tessera's museum in Rodano near Milano. Not exactly as the real thing ended up but gives you a good idea of the scale. The river Lambro flows through the middle and this is where the freeway now cuts through, over the river. The shot on the right is the same model in what appears to be the Innocenti boardroom. Judging by the Lambretta TV175 S1 I would put this at around 1957.
