This is the sight that greeted me after a 58 mile drive.After a couple of treatments of aircraft stripper and some Easy-Off oven cleaner I was able to get at the markings.For more detail information see Anvil's in America by Richard Postman (and More on Anvils when it is published): - If there is an oval depression in the bottom it may be either a Trenton. If there is a clear line/seam showning a top plate it would likely be a Trenton or Arm & Hammer.If the area under the heel is rough worked, it would likely be a Arm & Hammer.
Eagle is usually holding an anchor, perhaps because Fisher made many of the big ship and shipyard anvils for the U. - If you see what looks to be an arm holding a hammer on the side it could be either Vulcan or Arm & Hammer.Vuncans tended to be more blocky while Fisher's were more typically of the sleeker London pattern.Older Fishers had a handling hole under the horn and heel also, while Vulcan's didn't, and newer Fishers (after the late 1800s) usually had the mold pattern date under the heel.No seam, then I would suspect a one-piece cast Swedish. - If it meets the other criteria for one of the above, and it has no serial number, it may be one of their rejects sold on the secondary market.- If you see a series of numbers (serial number) on the front foot, it is almost certainly to be a Trenton, Hay-Budden or Arm & Hammer. Usually, but not always, it was due to an incomplete weld between the anvil and top plate.
