Hello, I'm very new to blacksmithing (I've yet to finish my first project - tongs). I bought this anvil from an antiques shop in the north west of the UK. There's not a whole lot of information I was given, other than that it was bought from a blacksmith who was using it for 30 years. It has no visible markings from what I can see, it's around 140kg / 308 lbs and has a good rebound of around 87%. Any help identifying it would be very much apreciated, thank you very much for your time!
