The Dubroni No.1 is a 19th-century French wet-collodion camera designed for in-camera processing, with the late outfit referring to a complete kit including the camera body and accessories. It is a small, handheld apparatus from the early era of photography, and surviving examples are sought by collectors of pre-dry-plate equipment.

Auction data for the Dubroni No.1 (late outfit) is extremely thin: a single recorded UK auction hammer result from 2018 sold for £720, which represents wholesale saleroom level rather than a retail or dealer asking price. With only one data point, today's value is best understood as indicative rather than a market median, and condition, completeness of the outfit, and provenance will heavily influence what a comparable example sells for.
