I haven't paid much attention to foreign safe ratings, so no help there. I did very recently open a very similar looking Swedish Tann that turned out to be a labeled TRTL30X6. If your safe does not have a UL burglary label,. I would use a 3 wheel S&G 6730 lock, and a big NO on using an electronic lock. Depending on door thickness, you may need a longer spindle than what normally comes with the lock.
