Hello, In a warehouse of an abandoned cinema I found some items, including movioles, and this in the picture below. I think it's a telecinema (it's working, it lights up, and the plates are running). But I'm a sound engineer, and I do not know these things. In the coming days, as I do not need it, I thought I would sell it. Kindly, someone can tell me what it is and if you think it have a market? Many thanks in advance. Giovanni Conti
