One of my husband’s friends and helper received an old Mosler Safe to junk. I was informed that there is no way to open this safe. The internet provides information which states that most safes of this type can’t be open even when dynamite is used. This is probably why the safe was given away and there may be nothing in the safe. The company who made the safe, Mosler, went out of business in 2001. I can try to find a locksmith, but it is not worth the time or cost. The safe is rusted out, and the men are in the back of the house. They have already removed the front part of the safe. I hope they find something worth finding, but if they don’t, they already have their treasures.
