The Rietzschel Stereo-Panorama Clack is an early plate camera produced by the German maker Rietzschel, designed for both stereoscopic and panoramic exposures on a single body. It is a pre-war collector item rather than a user camera, valued today primarily as a piece of historic German camera engineering.

Public auction data for this model is extremely thin: a single recorded UK saleroom hammer result, from October 2000, achieved £446, and that figure remains the only concrete reference point for what one is worth in the auction market today. With no recent comparables, the price a clean example sells for in 2026 would depend heavily on completeness, condition, and bidder competition on the day, and any value estimate beyond that single hammer record is speculative.
