The Lionel Linex is a subminiature stereo camera, a niche category of stereo cameras designed to take pairs of small-format images for 3D viewing. It was sold under the Lionel Mfg. Co. name as a consumer novelty stereo outfit.

Sales data for the Linex is very thin: the only recorded UK auction hammer result on file is a single sale at £215 in 2005, so a reliable current value range cannot be quoted today. Buyers asking what a Linex is worth in 2026 should treat that figure as a wholesale, saleroom-level reference point rather than a retail price, and expect actual results to swing widely with completeness of the outfit and condition.
