I recently acquired this anvil and need some help to try and identify the maker and weight if possible. It was acquired from a local steel mill that had in house forge shop that was being shut down and sold for scrap. The mill had been in operation for over 150 years, but not sure how old the anvil is. On the picture with the "405" stamp there appears to be another number faintly stamped in front of it. possibly a 3?? might just be nothing.
