The Zeiss Ikon Stereo-Nettel Tropen 614/9 is a tropical-finish stereo plate camera, built with teak panels and brown leather bellows for use in hot, humid climates. It is a folding stereo design from the early decades of the twentieth century, positioned at the upper end of the stereo plate-camera market when new.

Auction data for this Tropen variant is extremely thin: a single UK saleroom hammer result of £667 from 2003 is the only confirmed reference point, so a current price range cannot be reliably stated for 2026. Tropical-finish Zeiss Ikon stereo cameras are condition-sensitive at auction — the value of any given example today depends heavily on the state of the wood, leather and bellows, and on completeness of the original plate holders. Buyers researching what a Stereo-Nettel Tropen sells for should treat the 2003 hammer as historic context rather than a live guide to what it is worth.
