The Lizars Challenge is a wooden field/view camera sold under the Lizars name, the Glasgow optical retailer that distributed plate cameras in the late 19th and early 20th centuries. It is a large-format plate camera intended for landscape and studio use during that era.

Auction evidence for the Challenge View Camera is thin: a single UK saleroom result from January 2022 saw one sell for £174 at hammer (wholesale, before commission). With only one data point, today's price for a comparable example is best anchored to that figure rather than a range, and condition of the bellows, woodwork and any accompanying lens will move what one is worth in either direction.
