Welcome back, Arioch! Good to see another OTC video from you! I was recently able to work a deal on several plug leg irons. The largest is about 10lb. and has a partial stamp on it, that is no longer legible. The 2nd biggest is a Griffin and weighs about 6.5lbs. The 3rd one down is a Nichols and the bottom one is a Froggatt. All of them work, but one pair is missing its plugs and has the first set of threads on one of the cuffs, stripped out. A plug will not seat in that cuff. But the main part of the lock still works. I also was able to get a Thompson Plug Chain Handcuff, many years ago. Unfortunately, mine is missing the plugs, but works well. I was missing several plug keys, but a good friend of mine, who has a great small scale machine shop in his back yard, was able to replicate a few plug keys for me. Happy to say that he did an amazing job and the keys he made me, work great!
