In "Orkney, The Magnetic North" by John Gunn, first published in 1932, there is the following: "The next important channel separates the Mainland from the South Isles. It begins on the west as Hoy Sound, and then widens out into the expanse of Scapa Flow, with an area of more than fifty square miles. (Note that 'Flow' is pronounced to rhyme with 'how'.)" Now I've always pronounced "Flow" to rhyme with "show". Is the how/Flow pronunciation still the usual one in Orkney? Norman Tulloch
