The Bertsch Chambre Microscopique is a replica of an early French camera design from the mid-19th century, built in the form factor of a small box camera intended for close-up and microscopic photographic work. As a replica rather than an original period example, it is a collector's display piece reproducing the appearance of the historical instrument.

Replica examples are scarce at saleroom level: the only verified UK auction record on file is a single hammer result of £750 in November 2019, so any current value sits around that figure rather than a tested range. With just one data point, the price a Bertsch Chambre Microscopique replica sells for today is heavily dependent on the individual lot's presentation, provenance and which bidders happen to be in the room.
