Saunders-Roe (Anglesey) Ltd launched their first Minesweeper in 1954 around the time they were starting to build the Dark Class FPB's.
The Minesweepers:
HMS Brenchley M2004 launched 19/7/54
HMS Brinkley M2005 launched 14/9/54
HMS Chailey M2009 launched 12/11/54
HMS Cradley M2010 launched 24/2/55
HMS Pulham M2721 launched Nov 55
HMS Rackham M2722 launched 27/4/56
HMS Reedham M2723 launched 20/11/58 (fitted with experimental stabilisers in 1959)
Saunders-Roe laminated the timber frames and there is plenty of photographic and cine film records of their manufacture. The construction is also featured in a number the company magazines "SARO Progress" during the 1950's. I have managed to find thirty-five of them and have scanned them at photo quality to DVD with an interactive (hyperlinked) index to the articles. These magazines cover a wide range of products including flying boats, buses, MTB/FPB's, Minesweepers, launches, landing craft etc. They also cover their Cowes, Isle of Wight, Eastleigh and Anglesey factories.
