The Butcher Primus No.2 is an early 20th-century British plate camera sold by W. Butcher & Sons, a London-based photographic retailer and assembler. It is a folding plate camera intended for amateur use during the era when sheet and plate photography was the consumer standard.

Sales data for the Primus No.2 is very thin: a single UK auction hammer result from August 2024 saw one sell for £12, which sets the only current reference point for what this camera is worth today. At saleroom level — wholesale hammer prices, before commission — examples in this category typically trade as decorative or shelf pieces rather than as working cameras, and condition of the bellows, shutter and ground glass will determine whether a given example sells for the low end of that figure or a little above.
