Soligor movie equipment question

I am in St Quentin France. At a local market I saw an old movie camera with 2 lens. They are Carl Zeiss. So, the question is what might be the value? The market closes at 1800 France time. I know this is not the precise forum for the question, but perhaps someone in this forum will have an informed opinion and maybe I can snag a desirable antique for little cash.
