One shipbreaking book I have is Metal Industries. shipbreaking at Rosyth and Charlestown by Ian Buxton, published by the World Ship Society. It mentions Berengaria - she was sold to Jarrow Shipbreaking and Engineering Co at Southampton for L108,000, departed Southampton under own steam 6/12/38 and arrived Jarrow, Tyne on 8/12/38 with demolition commencing March 39. The hulk was subsequently sold to Shipbreaking Industries Ltd June 1941 for L43,500. Broke in two 12/41. Forward portion towed to Rosyth, arriving 24/7/46 and aft portion towed to Rosyth arriving 27/8/46. I guess Metal Industries lost on the deal since the sea sucked on the bones for about 4 1/2 years. (I contest Mauretania was worn out - outmoded certainly, but not worn out) Now I dodge torpedoes!
