There is a wreck that is often referred to as Rio X, but according to my sources this is totally wrong. ( Ref. Nordvard that is often referred to as Rio Y )
Can anybode help me figur out the correct identity on this one?
And the history under ww2?

From a typical Rio X web-site;
*This 320 foot cargo vessel served as a mothership for minesweepers during WWII before being sunk by a German magnetic mine in 1946. She lies outside Mortsund between 35 and 45 metres.
