I don't know about any planes on project for restoration for Sola. But this link
http://www.ju88.net/
shows a Heinkel 111 which were taken up from a lake near Trondheim two years ago. Pretty nice condition (fresh water lake..). Also there is some pictures of a Junker 88 which were taken up from 60m in the sea of southern Norway in 2000. Both planes are going to the german technical museum for restoration
http://www.dtmb.de/ . Hopefully they will be ready soon. Looking forward to that.
The Heinkel 115 I did dive on, probably has floats since it were sunk while moored in the harbour. Just about every place calm enough to moore a seaplane in the aerea around Trondheim were used by the germans to accomodate seaplanes during the war. The bottom which the wreck rests on is very soft, so the floats are probably sunk into the clay. Only part of the wings, some fuselage and engines are visible. The beautiful glass nose cone is missing along with the entire front part of the fuselage.
