5 brass porthole liners measuring 30cm wide (inside rim measurements) and 2inches deep. These were onboard my narrowing project boat already however they do not fit the in situ portholes so I am selling. They are possibly antique given the nature of the boat. They are warped in places but revert to round shape. Started to clean up they come up really lovely it is a shame they dont fit but hope they will find a good home.
