This original double-ended Scotch boiler from “PS Waverley”, the last sea-going paddle steamer to be built, was manufactured by Rankin and Blackmore of Greenock and installed in the vessel when it was built in 1947. It is now a rare example of a boiler of this type and size. Its impressive dimensions (over 5m tall) give a good indication of the size of the vessel’s engine room and machinery spaces.
