Boring old same old, or a bit better?

I went a bit overboard at a deceased estate yesterday and couldn't resist this set, which is seriously heavy. It's cut, and I hope someone here will say "xyzw, such and such a design", as I've seen happen before. I know decanters aren't of much interest and there are no marks on this one, but on the offchance someone recognises the shape of the glasses that'd be grand. (Thanks. The owners very kindly left a label on all their other sets -- most of them Czechoslovakia circa 1950.)

 

I'm tempted to say same, same old. Looks like a typical diamond pattern in lead crystal. The shape of the tumbler is interesting, though, especially at the base. That shape might be the key to an ID.

For me, the quality of these sets is very hard to judge just based on photos. It helps to feel the weight of the glass, and the refraction. I can't even really tell if these are pressed, cut, or a combination. I hope someone comes along who can be more helpful.

I don't think that these came together. The decanter looks pressed but the glasses look like they may be cut. The decanter looks like those you see inside of an antique Tantalus.

Those square decanters were VERY popular as wedding gifts in the 1970's. I know, because I received FOUR of them, all different. The square ones were often referred to as "whiskey decanters" at that time.

(I received several other decanters, as well, that were not square. Decanters & crystal salad bowls seemed to be the 1978 wedding-gifts-of-the-year!)

Note that the round, faceted stopper is less common on these square decanters than either a square stopper or a "flattened" disc-shaped one - or even, sometimes, a plain round ball.

That said, Gorham, Villeroy & Boch, Galway Crystal & Waterford (and undoubtedly others) all had their versions of the square shape with round, faceted stoppers.

As for the glasses, they look almost like juice glasses to me, but I don't drink liquor, so who am I to say? Glencairn calls this The Ultimate Whiskey Glass:

and it's not like anything I have ever used to serve whiskey!

Wish I could help to ID your decanter & glasses, but I certainly don't recognize them off the top of my head, and I wasn't able to find them in my search.

 

I think it is my dubious photography and that it is a set, but many thanks for your comments everyone. Decanters are stone dead Downunder just now, but the weight of this lot intrigued and it was a house with some interesting stuff. It was a long shot, so thanks again.
