I found it --
"I only found a few of my collection [of Euro sparklers] in Germany, while I was there, the rest of it, I've found in France, every summer we have holliday in France and of course I did my homework there. For me it is 100% sure that the European Sparklers were also made in France, and I think most of them.
"In the south-east of France, there is an area, that's looks very much like the area around Lauscha Thüringen, also this area is famous about it's glassworks, for example the presse papiers were made there. The sparklers must have been made, in, or close to the village of Biot, in the middle of that area.
"More then once, this was told me by an antiqairian. Also the marbles here were made in the same way, as they did in Germany, by leftovers, kind of EOD's.

And a little later --
"About the [other] sparkler types, I really don't know where they have been made, I can found them in so many European country's and there are so many different type's at this moment I'm a bit lost. I've a sparkler type with Bonux printed on it, i've also one with Bonux engraved,think the engraved one is older.

I have one with printing on it but I think mine says AJAX instead of BONUX. I'm old. I forget. I'll look tonight.
