They are as they have their weights scribed into them. They were truncated to make bollards they are on 2 tonnes each would have been 3! Will post a pic of their scribed weights on the channels post note 57 was number or hundred weight (each was 112lbs back in them days) then quarter hundred weight next number then remaking pounds all carry their proof mark (an carved in arrow) too! 👍 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dZylDhCGwSs.html
