Blenko tall vase?

I sent info and pics of this piece in to the Blenko project a while back, and finally heard back today:
"Its not a catalog piece. We can't confirm or deny it is a an end of day or designer artist proof.
Weight and feel ? Is it heavy"

I also posted on the PGP board a while back. Just my luck, oh well.

Measures: 19.5" high, body/bulb is 22.5" around, top measures apx 4" across.
Weighs: just about 3lbs

I was researching a swedish/scandinavian piece recently and found these vases, the bottoms seem to be shaped a bit different, but its very close, what do you's think? http://www.20thcenturyglass.com/sto...d=4004&zenid=a40ae8d72af24386a15f4acd03cf45e4
