Featured Silver & glass cake stand, help with marks

Your photographs are good, Davey, with an in focus view of the marks.

Yes, it is a horse's head, the Yugoslavian import mark for .800. So there is a Yugoslavian link, but it wasn't made in Yugoslavia.
My guess is it was made in neighbouring Italy and exported to Yugoslavia.

 

And it will do its best to impress.

 

Oddly, the glass part looks American. Might well be - ships went both ways. American bright-cut crystal on a probable Italian base, exported into Yugoslavia (Austria-Hungary at the time?) and then chucked in a duffle and hauled to the UK. That thing got around.

 

It's a beautiful piece.

 

It is a pretty generic cut, which was also made in Europe. It may even have originated in Europe.

Extremely unlikely, especially when Yugoslavia had a glass making tradition, and it had crystal and glass manufacturing regions of world fame to the west (Italy), and further north (Bohemia and Germany). The silver is likely Italian, the glass could be too.
American glass and crystal are a local thing, and virtually unknown in Europe. Europe exported glass and crystal to America, not the other way around. Only Europeans who have lived in North America will have come across it.

Yugoslavian marks were used in Yugoslavia, so they can't have been used in Austria-Hungary.
Yugoslavia is a 20th century post-Austro-Hungarian nation name which means South Slavia, an independent geo-political union of several south Slavic nations and regions. This union began to fall apart in 1991.
So Yugoslavian by definition means post-Austria-Hungary, post-Ottoman Empire, post Kingdom of Serbia, etc, etc.

 

I wasn't sure when the marks changed over. The tazza still got around a bit though. I even saw a bit of Yugoslav glass here in the early 90s for a while, but the Chinese took over the market by the late 90s.
