Eder Patent
The Eder Patent is a German-made camera. Sales records list a single example sold under the Eder Patent name, and detailed model documentation is not available in the data provided.
At UK auction in November 2025, an Eder Patent fetched £3,200 at hammer — the only verified saleroom result on file, so this single figure currently anchors what the camera is worth today rather than a true market range. With just one data point, the price a comparable example sells for could vary materially depending on condition, completeness, and bidder interest on the day.
Sales History
Prices shown are UK auction hammer results — the wholesale level achieved in the saleroom. Neither buyer’s nor seller’s commission is included. Dealer and retail asking prices are typically higher.
