Hello! New user to this site here. I came across some antique padlocks recently and I was able to identify them all but one. I am attaching images of my lock and some others that look very similar other then the brand name on them. The only markings mine has are "Hardened" on the shackle and "Portugal" right beside where the shackle goes in. From what I have found it looks very similar to some "Yale" brand locks. Any help will be much appreciated. Thanks for checking this out and have a nice day!
