A recent acquisition, this should interest Fred, although it is nothing like as exotic as his sliding box camera by the same maker. This was made post 1861 when the Prince Consort died, as the label refers to him as the "Late". It was evidently after Chadburn had brought his son into the business; from what I can gather he started trading as C H Chadburn.
It is of very high quality construction with dovetailed corners and inset hinges and brasswork, but marred by having paper bellows, which seems an economy too far; or maybe paper bellows were normal at the time it was made? Pictures in Eric Evans Album on this site.
