Thanks Jeff! I didn't want to 'bias' the conversation, but I should mention that based on Dad's career, I expect it would be for a room or file-cabinet or safe that would be found inside a secure government facility. A lockable filing cabinet (or safe-deposit-type box) from the 50's would be my first guess (without any real data on my part). As for security, it perhaps would NOT need to "stop a bad guy", but rather to prevent other personnel in the facility from getting into something if they didn't have the correct key in-hand. I have a bunch more random keys from Dad's things. I'm going to see if there's another of the same style that still has the original markings on it.
