New Toy. I don't think this is a round anvil but, a round anvil is what it's going to be used for. I was at the scrap yard today and was about back to my truck when I spotted it. It's steel and NOT cast. I've hit it with a welding slag hammer and didn't even mark it. Also hit it with my 4 lb hammer and didn't mark it. It's sitting next to a #150 Hay-Budden for comparison. I'm guessing the weight is around #100 or more.
