Heavy Glass Vase - Controlled Bubble Swirl Pattern

Hello everyone! I've got another mystery vase I could use your help with. It stands just a little over 5 3/4" tall and about 2 7/8" across the opening. Very heavy for it's size. It's a kind of a greenish yellow color but does not react to a blacklight. Lots of scratches on a completely flat bottom. Any help towards origin would be much appreciated! Thanks!

OK--let me preface this with I don't know much about this kind of glass...but the color and bubbles remind me of West Virginia made glass...(though the shape does not ...

 

Done a little more searching around - Could this be Erickson in their champagne color?

Could be Erickson if the shape is right.

 

I thought Erickson, too, because that is a color he used so often. The Georgian in Lancaster, Ohio, has a nice collection of his glass and if you get the right person they will even answer questions about the glass. The glass museum in Lancaster is worth a visit, too.

 

I do not spot this shape in Knower's book on Erickson.

 

Hello everyone- thanks for your opinions and George, for checking your book. I've got a lead on an Erickson collector through the Blenko Collectors Facebook page and am going to try contacting him. If that doesn't work I'll try and swing by Lancaster the next time I'm in Ohio.
