What kind of safe is this? It was here when the building was bought in the 80's, and before that this used to be a factory going back into the 1800's, but I'm thinking this isn't that old. We have a business on the floor below, and I don't want to disturb the girls working down there (it's an answering service, so they need their quiet), so explosives are no-go. If I can't fiddle out the combination, where would I drill? I don't own a torch of any sort either, and I've heard these old safes have asbestos lining sometimes, so that kind of terrifies me.
