Steve,What information are you looking for? As the lock says, it’s a Yale. The fact that it has no other name or initials cast or stamped on it leads me to assume that it was just for retail sale. It’s not a rare lock, but not a common lock either especially having a working key. Yale started in business around 1868 in Stamford Connecticut. As to the year yours was made, it’s hard to say with any certainity. But I would think the early 1930’s to the early 1950’s. Value is another thing that’s hard to say. There are collectors that only collect Yale locks and others that collect brass locks or lever locks. This lock might be worth more to these collectors, but either way it is worth at least $35.Hope this gives you a little info. Mark
