Beautiful 7” Smoky Gray Crackle Glass Pitcher ( Pilgrim?? )

No damage, did show a photo of an air bubble on the bottom, sold as seen in photos, about 7” X 5” at base and 4” at the mouth. I’ve had this piece for a while and I give up trying to figure out the maker, I have no clue, any thoughts or insight would be be greatly appreciated, I know it’s not benko, my best g is pilgrim.
