The Perken Stereo is a stereoscopic plate camera produced by the British optical maker Perken, Son & Rayment. As a stereo camera, it was designed to expose paired images on a single plate for viewing through a stereoscope, a format associated with late-Victorian and Edwardian photography.

Sales data for the Perken Stereo is extremely thin: a single UK auction-hammer result from 2010 stands at £800, which is the only data point on file and reflects a wholesale saleroom level rather than a retail asking price. With no recent comparables, what one is worth today depends heavily on completeness, lens condition and bellows integrity, and a current price could deviate substantially from that historical figure. Buyers researching what a Perken Stereo sells for in 2026 should treat the £800 figure as indicative only.
