My father was a skilled blacksmith. I have his Nohab 18 anvil. I have learned a bit about the Nohab manufacturing company and their anvils....enough to know that they are somewhat rare and of good quality. Dad's anvil is marked "18". I have seen a "13" described as weighing 135 pounds and I know this one is around 200 pounds. Using the ratio of 18/13 and the 135 lb weight of the 13, I guess the weight is 209 pounds. Would welcome comments and also suggestions about how and where to sell the anvil online. Thank you.
