Javier, that's exactly what I thought, but someone who is pretty knowledgeable about Erickson glass said no, not Erickson.
David, I do have a photo of the base, but it's a little blurry. The bottom is ground and polished flat with no bevel, no indent. The wear would be appropriate for mid-century or so. These photos are quite old, and pretty bad. I will definitely take some better ones later!
