Certainly hasn’t been milled, there’s a waviness to all the sides but some definitive striations from a grinder, I just joined my local Blacksmith’s association so I’ll be bringing it in one day for them to take a look at, but I’ll just be practicing at the shop so I won’t be needing to use mine for sometime which gives me plenty of time to get a feel for how I’ll want my anvil to be when it comes to that time
