As I am rebuilding an 1880's Ross of London, Tailboard camera,(most likely built by Meagher), I remembered a photo album I have of a voyage onboard HMS Wild Swan 1885 to 1887.
It show's what I believe is the lens board off the camera that was used on the trip. I have been looking at many vintage mahogany cameras and non quite match.
It would be quite novel to know the exact camera that was used at sea.

Cheers
