The Contessa Duchessa is a folding plate camera produced in the early twentieth century by the German maker Contessa-Nettel of Stuttgart. It was offered as a small-format folding camera for amateur use during the era when strut-folding plate designs dominated the market.

With only a single recorded UK auction-hammer result available, the Duchessa is rarely traded and lacks an established price band; the one documented sale in our records fetched £92 at auction. On that thin evidence, today a clean folding Duchessa is worth somewhere in the region of that figure, though condition of the bellows, shutter and ground glass will move the value considerably either way.
