The Contessa Deckrullo Nettel Tropen Stereo is an early-20th-century stereo plate camera made in a tropical-finish variant, using polished teak and lacquered brass in place of the standard leather-covered body. It was built for stereoscopic plate photography and sits in the upper tier of pre-war Contessa-Nettel folding cameras aimed at serious users working in hot or humid climates.

Auction data for this model is extremely thin: a single recorded UK hammer result in August 2023 saw an example sell for £650, a wholesale saleroom figure that excludes commission. With only one data point available today in 2026, that £650 sale is the only reliable reference for what a Deckrullo Nettel Tropen Stereo is worth, and condition of the woodwork, bellows and shutter will swing the price materially in either direction. Buyers asking how much one sells for should treat £650 as indicative rather than a firm market value.
