I have learned of a ship called SS Tynwald which was in Belfast and then taken into Naval Service in April 1940. Work was completed on making her suitable for Naval service in November 1941 but then she was sunk on 12th November 1942. Does anyone know anything about this ship and what it was used for? Also:- The "Jewel" - All the info I have is that it was built in 1908 and R. 84t (Whatever that means??) She was mined in Belfast Lough in 1941. Was she a cargo ship? Were there any losses?
