The Krügener Engel A is an early German plate camera produced by the Frankfurt maker Krügener. As a wood-and-metal plate-format instrument from the late 19th / early 20th century, it sits in the collector segment rather than the user-photographer market.

Sales data for the Engel A is extremely thin: the only recorded UK auction hammer result is £300 from 2005, which provides a single wholesale data point rather than a reliable price band. With no recent saleroom comparables, today's value for a Krügener Engel A is best treated as indicative, and what one sells for now will depend heavily on condition, completeness and bidder interest on the day.
