I’m researching info on antique anvils to try and help my Dad figure out some details on his. He bought it about 10 years ago. We live in an area where the coal industry in prominent, so that’s what we are guessing it was used for. It has a pretty clear 25 on the end under the horn. And something like a date stamp on the opposite end maybe with a symbol before the date. Maybe gonna try chalk or something to reveal other markings. Two men have to lift so we are guessing around 300 pounds.
