Hallo

I'm having problemes with the former british trawler Rutlandshire 458 BRT.

She was salvaged and got the name Ubier ?

I have the names Ubier, NM-21 and V-6116,
the seizes of 304, 358 and 458 tons
sinkung dates (mined) of 06.12.1942 and 12.12.1942
mine laid by the russian submarine K-1 or unknown


This is too much confusion for me.
I need help by sorting because i'm thinking that this are facts of at least two ships.

Thank you
Axel
