It will not be used for valuables. I can't get a clear answer from anyone (some don't answer the phone at all).. about replacing it with a new dial. Not absolutely sure its even possible to do so.When was the safe made, it looks vintage. If you've done due diligence by calling 8 or 10 vintage safe experts, and they can't refurbish the lock, did you ask them about replacing it? Basically, the lock and handle could be converted to a new handle and lock most likely. I have a vintage safe and was told by experts they are NOT secure at all compared to modern.
Otherwise, Maybe use it for a decorator safe or have a safe expert kludge something cosmetic that will close, maybe adding a padlock too. Old safes are not very secure really, they're more for looks. Even new safes can be entered in about 10 minutes of work.
