Hartismere was built in 1947, 5,719 Tons Gross, Length 457', Breadth 60', motor ship, single screw, service speed 12 knots. Described as a General Cargo vessel so pretty much a tramp steamer carrying almost anything except liquids. Still with J & C Harrison in 1958 but no longer listed with the company by 1964. By then the company was running 4 sister ships all of 9,100 GRT, 2 built in 1958 and the others in 1959. I don't know what the Hartismere's eventual fate was, my reference library doesn't provide any more details. Hope the foregoing is of some interest.
