Trying to figure out what this key would have been for. My dad found it where he dug up trees years ago whom the owner called "The Four Brothers." The owner was pretty interesting and would be the type that would hide treasure. House was built in the early 1950s. There is a farm house which was his wife's parents next door. That house was built in 1895. In the 1970s his wife's family sold the rest of the farm to be developed for the current neighborhood around the farm house and where my parents live. So, any clue what this key would have been used for?
