Rollei Rolleidoscop (4x4)

{"overview":"The Rolleidoscop is an early stereo roll-film camera produced by Franke & Heidecke, the Braunschweig firm that later became known for the Rolleiflex twin-lens reflex. Because this is a wholesale saleroom price excluding commission, retail asking prices from specialist dealers in 2026 typically sit higher, and condition of the bellows, shutters and matched lens pair drives most of the variation in what examples sell for.","buying_guide":"Stereo cameras of this era commonly suffer from light-leaking bellows, sluggish or sticky leaf shutters, and haze or separation in the paired lenses, so both optical assemblies must be inspected together — a mismatch makes the camera far less useful.
