Mackenstein Jumelle

{"overview":"The Mackenstein Jumelle is an early French stereo-format plate camera, produced by the Paris-based maker Mackenstein in the late 19th and early 20th century. With only a small number of saleroom results on file, what a Jumelle is worth today depends heavily on completeness, plate-holder inventory and cosmetic condition, and individual sales can fall outside that band.","buying_guide":"Inspect the twin shutters for matched speeds, check the leather covering and wooden body for shrinkage or separation, and confirm that both lenses are clear and free of internal haze.
