Featured Blue Glass Bowl with Lightly Crimped Rim

Hello everyone! Can anyone help me identify who might have made the bowl and when. It measures about 5 3/4" across the rim and 3" tall. The center of bottom (pontil?) is not perfectly round. There is an area of grinding roughly an inch wide circling that bottom center. I'm assuming it's blown into a mold and hand tooled? It's a very pretty shade of blue which reminds me more of a mid-century color than earlier. There is a lot wear/scratches along the base. Any help would be much appreciated. Thank you!
Don

 

Is it possible that this is a squat vase?
I am just guessing, but would it be Viking glass.
Pretty color Don.

I miss your hat avi.

 

I don't know who made it, but I can say that the way the bottom is finished points away from Viking. The bottom also pretty much rules out the West Virginia glass makers such as Blenko, Pilgrim, Bishoff, etc.

 

Thank you, pearls! I should have my Christmas hat out soon. And thank you msgood2shoe. I will have to accept that I just have a pretty blue bowl!
