The Zion Simili Jumelle is an early French-made jumelle-style stereo/detective camera, a body format produced in the late 19th and early 20th centuries and styled to resemble a pair of binoculars. Zion offered it as a compact plate camera aimed at amateur photographers of the period.

Evidence of what a Simili Jumelle is worth today is thin: only a single UK auction hammer result is on file, a 2015 sale at £500, so any current price guidance is indicative rather than a reliable median. Condition, completeness of plate holders and the state of the shutter all materially affect value, and at saleroom level a clean, working example would be expected to lead the market while incomplete bodies sell for considerably less.
