Maybe an Aley exotic coral, but Champion made them too

Ho trovato quello menzionato da Al Oregon, ma non ancora l'altro. In quale foto è la seconda? 

Oops, I don't know why I said two ... just one, bottom right

Yes, including a pair of pelts

No, they seem to add colored powder to the dough, before making it

Good chance of vitro

Pelt

Ravenswood

I also think European

Colored agate

Yes, possible pelt

I think about Heaton without being sure

Peltier bello

This, on the other hand, is the typical exclusive example of Heaton, with these beautiful colors!

Cairo and Heaton are very similar, since they were partners with the company as well as brothers-in-law, therefore, after their separation they used (if not all) the same glass.

However, there may be features that can distinguish them, namely; the famous and somewhat vulgar (so to speak) "BUTT CRACK" known from the Cairo structure, later also attributed to Jabo "classic"

In Heaton on the other hand, it is the typical "ear" shape in the swirl that distinguishes it from other companies.....you can see it in my group photo, the red one at the bottom center.

The marbles of both companies are rather transparent and translucent rather than opaque, but in any case there are also the latter.

Yellow seems to have been used more by Cairo than By Heaton.

Then, each of these companies, to its own typical exclusive marble in absolute, namely the "red lightning" of Cairo, with glass type "GEL" and with large bubbles.

To Heaton? I don't remember the name, maybe "red rose", (similar to Ravenswood's red raven) but I know for sure that there is an unnamed marble (I think) with Heaton's exclusive colors ..... then I show them.

Then, with a little experience you will notice other tricks, although of course in some it will be impossible to distinguish them.

Below, I'll show a typical and maybe HTF "red lightning" of Cairo

Shooter, although not in perfect condition

Yes, I recently found some Heatons (oddly enough) and probably two Cairos in my area.

They are not easily found by us, but every now and then you can come across something nice, like the Akro shooter that I found about 15 days ago

Heaton/Cairo

It could be Heaton or Cairo, more easily Cairo, certainly not veiligglas

Imperial, nice!

This measures 0.905 / 23mm

I have one similar to that of yours first, with thin white thread, then I show it ....

100% wire-pull veiligglas, as well as the other three in hand

Then I see vacor, two red devils etc.
