Stirn Vest Camera (4 exposures, 4x4cm, box)

{"overview":"The Stirn Vest Camera is a late-19th-century German concealed detective camera designed to be worn beneath a waistcoat, with the lens protruding through a buttonhole. Hammer prices at saleroom level reflect wholesale conditions rather than dealer retail, and values are highly sensitive to completeness of the original case, plate holders and mechanism condition; a single data point should not be read as a definitive market range in 2026.","buying_guide":"Inspect the wooden body and leatherette covering for splits, the rotary plate mechanism for free movement, and the shutter and lens for damage, since service support for cameras of this age is effectively non-existent.
