This anvil appears to have an unusual arch under the main body.  I know the picture is poor quality, but does anybody have a guess as to the maker?

Due to the quality of the photo, the picture angle, etc. it is difficult for me to tell if it is an arch or the curve between the feet. If you are able to get additional photos, and photos of any marking, it would help us provide an opinion. As to the maker, there is just not enough information to make anything other than a guess.  If someone recognizes the anvil shape or outline, please provide an opinion.

Grabbed it off a website, may or may not see the anvil but was intrigued by the "arch of the base.

 

I'm in Shelby Co. Ohio 

The arch may just be the angle of the photograph and the curve between the feet creating an illusion.

Spanish and French anvils sometimes had an arch in the base; but I concur it looks the the curve between the feet to me.

The horn looks a bit off to me. I'd certainly want to see and test it in person before making an offer on it! (If that is what you had in mind)

Quad-State Blacksmiths Round-Up is coming up fast at the Miami County Fairgrounds, Troy Ohio.  There will be several HUNDRED anvils for sale and so on display there if you want to see a bunch and get a feeling for them.

Saw that one as well.  It's like the estate sale people don't even look at some of the pictures they post!
