This week's photo is of the ps Lucy Ashton. She was built in 1888 by Thomas B Seath of Rutherglen, and owned by the North British Steam Packet Company, first working on the Holy Loch service and later steaming between Craigendoran and Gareloch.

She made her final run in February 1949. After that, she was sold for experimental use by the British Research Shipbuilding Association, during which she was stripped to the hull and fitted with jet engines. She was finally scrapped in 1951.

The name Lucy Ashton comes from Walter Scott's historical novel, The Bride of Lammermoor.
