I picked this up yesterday on the cheap, but I think it is very old.

Any help with maker or age?

No markings that I can find

Feet look old but the face/horn looks odd; does it ring?  To me it looks a bit like someone welded a face on it and ring would be a good indicator of if it's a full penetration  weld.

Now if they ground down the face to get it that clean they have almost certainly ruined it.

How much does it weigh? What are the dimensions? Like Thomas said the face looks odd.

It weights right 105 lbs.  It doesn't look like the face was milled or ground off.

 

I'll get some better pics.  The horn underneath looks very crudely forge welded on. 

 

A man whom I respect for his knowledge  of colonial and older anvils suspects it was either an early American anvil made in Boston in the early 1700's or even older and used by the French near Detroit.

But the face doesn't look like 300+ years of use or storage!
