Although the box says "Weiser Lock Installation Tools", it seems these tools would be more appropriate if you were breaking "into" a safe, rather then installing a lock on a safe, but that's just my opinion. I found this toolset, in a old Amish barn, several years ago. Obviously its old, probably 1950's but I really haven't been able to find much information about it. I do know Weiser locks began in 1904, by making custom locks for the motion picture studios, set designers. By the 1950's, the company had moved to Canada and are still one of the biggest lock manufacturers in the country. If you do a search online, you will discover that this set is available "no where". There was a listing on Ebay for just the box but no tools. This is almost complete & rather heavy for its size. $150.00, with free shipping for domestic U.S. residents.
