The mystery ship in April was the Turkish cargo vessel Halis Kalkavan, built as Baron Graham of H. Hogarth & Sons. The ship was completed in November 1925 by Napier & Miller in Glasgow for Hogarth, and was one of a series of similar ships built by Scottish shipbuilders in 1925-28. The four ships completed in 1925 had identical dimensions, but only Baron Graham came from Napier & Miller. Baron Graham survived the war and was sold to Schulte & Bruns, Emden in 1950. In 1954 the ship was disposed of and renamed Huseyin. In 1959 the ship was sold to an Istanbul company and renamed Halis Kalkavan. After service in the Mediterranean she was scrapped at Aliaga in 1982. Peter Cundall
