So basically I was looking to get into the hobby. The other night i was driving home and have been looking for an anvil in my price range for awhile now. When all sudden, next to someone’s trash is this anvil. So I pull over get the anvil and continue on my mary way. I clean all the rustoff, it had definitely been kept outside, and uploaded some pictures to Reddit/r/blacksmith hoping for some info. They were pretty knowledgeable and said that that looks to them like a very old "Mouse Hole" and directed me here for further info. Any help would be greatly appreciated.
Here is an album with some pictures.
