Small crackle class pitcher - Blenko, Pilgrim?

I picked up a few pieces of glass this weekend at an estate sale. This is one of them. It's 4.5" tall and 2.75" wide at the bulbous base. I've searched the Internet and it looks like it could be either Fenton or Pilgrim. It's made really well, but the pontil is rough. If anyone knows what this is, I'd love to know! I'm new to collecting crackle glass.
