The Houghton Ensign Carbine is a British folding roll-film camera from the early 20th century, made by the Houghton company in London. It was sold as a portable, pocketable folding camera for amateur photographers of its era.

Sales evidence for the Ensign Carbine is very thin: the only recorded UK auction hammer result on file is £69, achieved at Christie's in 1999, so any current value estimate would be speculative. Today in 2026, prices for early British folding cameras of this type vary widely with condition, bellows integrity and completeness, and a single decades-old saleroom result is not a reliable guide to what one is worth or sells for now.
