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.

How much does an Eder Patent sell for at auction?
The available sales history shows one hammer price of £3,200, so that figure is the best current reference for value, though it should not be treated as a reliable range.
