My dad and I started taking blacksmith classes in early April, and have caught the bug BAD. Dad remembered that his dad, my grandpa, had an anvil, and after some talk with my uncle, they tracked it down. It was sitting behind a shed near the Iowa river. They got it loaded and Dad brought it up to me to use, along with my great-grandfather's post vice that is still in great shape. I took it to class and our instructor noted that it was a Hay-Budden. We didn't dwell on it long because there was iron to forge! But he said it was a good one. That lead me to do some research, but I still have a couple of questions. Underneath the makers logo are the numbers 1, 9, 7. I'm guessing this is #197. I took some pics of the serial # and it looks like either 55008 or 33008. Another odd thing. I have learned that H-B's have oval impressions in the bottoms. This one has a square hole that is about an inch x an inch. Can anyone help me ID a date of mfg and any other info? Thanks so much!
