Very Large blown decanter Blenko??

I bought this at a yard sale. I was literally driving by with no intentions of stopping the lady was picking up after her day with what appeared to have been the first day of a three-day yard sale as I drove by the sun reflected through this bottle and I turned and meet Lee pulled over it was this decanter reminded me of a bottle that my grandparents used to have up on a shelf inside a big display cabinet along with all kinds of other things I bought it completely because it reminded me of my grandparents at that moment and it was good well that's now the decanter I've had four I've had it for probably 15 or 16 years and didn't think much about it until I saw an amber colored one that said it was Blanco and then when I look that up it has a green one that was just smaller then the one that I have it hasn't really matter to me it was more sentimentality I paid $3 for it it's 11 inches wide at the widest point 12 inches to the top of the vessel 15 with the fantastic stopper

I would love any input;)))
