Rollei Rolleidoscop

{"overview":"The Rolleidoscop is a roll-film stereo camera produced by Franke & Heidecke, the German firm that later became Rollei. Introduced in the 1920s, it was positioned as a premium amateur stereoscopic instrument, pairing two matched taking lenses to record stereo image pairs on roll film. Because the camera is nearly a century old and turnover is thin, each sale price tends to reflect condition and completeness more than any headline trend.","buying_guide":"Inspect both taking lenses for haze, separation and cleaning marks, and test the leaf shutter across all speeds since capping and sluggishness are common in cameras of this age. Check the folding bed, viewing hood and film transport for play or damage, and confirm that the leatherette, nameplate and any original case or film spools are intact, as completeness materially affects what the camera is worth.
