The color is consistent with Davidson for the time period it was made and I was always led to believe it is a Davidson piece. I have this exact dish. The feet, the concentric circles on the underside of the feet, are all consistent with Davidson. While that is not proof, and I have no catalog pages to prove it one way or the other, it would be safe to advertise is as 'most likely Davidson', which would get your search word in the description. I have also seen the swirl piece with 3 handles, two handles, and no handles, and all of them have the concentric rings on the underside of the feet, as do similar other pieces that are known to be Davidson. Hope this helps. Oh, and whether it has 2, 3 or 4 handles, I have seen different shapes that it was bent into after it was pressed. This naturally means that there are collectors looking for all the different shapes a particular piece was made into. This particular 'bend' is a bit tougher to find than others with 4 handles.
