Dallmeyer (J.H.) Stereo (sliding box, wet plates) Universal

{"overview":"The J.H. Dallmeyer Stereo Universal is a 19th-century sliding-box stereo camera built for wet collodion plates, a format that placed it firmly in the studio and field photography of the Victorian era. These are UK saleroom hammer results — wholesale levels, not retail asking prices — and as of today values for early Dallmeyer stereo apparatus remain heavily condition- and provenance-driven, with completeness of the original lens pair, plate holders and box being the principal price drivers.","buying_guide":"Inspect the mahogany sliding-box body for splits, shrinkage and warping that would prevent a light-tight fit, and check the bellows-free sliding mechanism moves smoothly without play. The matched pair of Dallmeyer stereo lenses is critical to value, so confirm both barrels are present, correctly paired and free of internal haze or separation, and verify that wet-plate holders and the ground glass are original rather than later replacements.
