Crystal carafe from the USSR era

Crystal carafe without defects from the USSR from around the 70s for strong drinks without a crystal stopper. Somewhere there is information that it's an Iļģuciems carafe, but I can't find 100% reliable confirmation. Occasionally, a crystal stopper can be found or someone has a stopper and is looking for a carafe. Glasses of various sizes with this engraving are often seen for sale. I send responsibly packaged, the costs/shipping of the parcel are covered by the buyer.
