Pottery Pitcher and Mugs

I love vintage pottery and found this pitcher and mugs but am having trouble identifying the maker. I had originally thought it might be McCoy since the marks on the bottom of this one piece look like the early NM; most of the pieces are unmarked. However, I was unable to find the handle shape in any pieces of pottery I had seen...until I looked at some Uhl Pottery pitchers. Any insight/confirmation of the maker would be greatly appreciated! Thanks!
