I asked a collector of marbles who lives on the border of Germany and yes, as Ron also says, no document has ever been found that they were also produced in Germany, one can only suppose. The guy I spoke to thought they were also produced in Germany, the most beautiful, densest ones, because he often found them in Germany along with German slag and even German artifacts. Perhaps, it seems, they were produced even before the Second World War

It's the same, but the op is in a different light, very strong...

Conqueror made to swirl

Alley

This one, for example, appears to be similar to your first one and seems to belong to the exotic, to the patch but not for sure, it has small features

The fact is that there are many color combinations, (perhaps still unknown) that leave perplexity and cause for debate. The only way is to post and hear various opinions to have more certainty

Fancy = colored transparent base, generally dark amber or green, with 2 or three colors with possible traces of white Exotic = neutral transparent base, or light amber transparent base with 2 or three colors including white The difference in my opinion is that the fancy have a more colorful transparent base than the exotic ones

Well I think there are some very obvious, safe exotic and fancy,conquerors, others may be similar (by color combination) without having a total certainty

I think the ones I've highlighted fall into this category of exotic or fancy, but it would be better to have individual photos

Exotic conqueror

Anyway, the question of white is a bit subjective in my opinion, everyone thinks in their own way ....

Yes, good question Ric In the past, the issue of white has been a matter of debate. Now, if in a marble the base is white and contains two colors, it is NOT tricolor but two colors , while, if the base of the marble has another color than white, white in addition to other colors, does it count as color ok? So, in my opinion, white in conquerors (fancy and exsotic) counts as a color, especially if it contains little.

Exotics and fantasies in my opinion are very similar, except that the former have (usually) a transparent or slightly amber base, type champagne and multicolored on the surface, while the latter, in addition to having multicolored on the surface, can have a transparent dark amber base (as in the case above) or green etc. I can't say more about it. Here is my shooter similar to the op, while the second and another fancy.

Asian

The big one (shooter) the second in the first photo, if amber base is a fancy conqueror vitro

Not really tricolor

I would say yes

Champion

Especially the first and last image tells me jabo

X 2

The structure is that, but the size is a little excessive for Heaton though ..... hmmm
