Gentlemen, The safe does not have a U.L. label. I did contact a gentleman by the name of Mike Palmer, i was told that he worked for Tann many years ago. After forwarding him the info that i uploaded on this forum he told me that this safe was marketed in Europe as the Tann Super Treasury which was the precursor to the TST range of safes. He also advised me that the security rating was a grade five. Safeman, thank you for posting the information on the Swedish Institute V3 security information, After some more research i discovered that the Tann TRTL30x6LW has the exact same measurements as my safe, even the weight is the same. Does anyone know what year Tann was awarded the 30x6 rating. Just Curious. I have decided to put the 3 wheel S&G on the safe, that plus the 9 lever keylock is probably more than adequate for my home. I would sincerely like to thank everyone for there help and information.
