I don't use a uv flashlight or light anymore. I use an old fashioned blacklight incandescent tube ( hand held or I also have a 4 footer) no uv reflection and it gives a much better glow, it'll show some stuff that a uv flashlight shows absolutely no reaction to, for example the slight green glow of the base glass in my sulphides.

Alley, Akro, IMO

Sony handycam camcorder, a tripod and a lot of retakes

Not Akro IMO

x2, Jabo

Nice bunch of Onions David

A 23/32nds Caged Clambroth from my old collection for this "Thüringen Thursday" ...

Looks Jabo to me, not many other mibs have gold frit like that @Nantucketdink would be the go to on this one, he's got a very extensive collection of Jabo and knows the runs quite well. Here are pictures of the 2008-2012 contract runs, I tried to find your exact marble through google but way, way to many to look @ for my small mind. Something for you to take a gander @ maybe you'll see something you'll like.

Agree w/ Ravenswood

Alley IMO

I don't think the OP ids even a Pelt IMO, yes all citruses have a white translucent base generally w/ some transparent. PELTIER CITRUS LINK :: https://www.peltiermarbles.info/citrus

Lazy corks are those that don't make a full rotation between poles i.e. fall far short, often confused as a patch.

I have corks that twist both ways, it's about a 50/50 shot last time I actually checked. Right and left hand twist applies to handmades not machinemades IMO These two Akros twist twist opposite ways.

Both Vacor IMO

Akro, machine made IMO

I agree Vacor but I'm not sure what, they're are so many variances between runs sometimes it's hard to tell exactly what it is ?? Here's another possibility !!

Attn, @bumblebee or @Steph I have on occasion run into this also, a temp. glitch ?? I've always been able to restore but still it shouldn't be doing it, just making ya awares, I thought it was me or I was the only one it was happening to. Not all that often & not in a while but it has happened. @bumblebee would be our go to for a fix or some investigation into the matter.

The opinions on being a Bronze zebra seems to vary widely, the one I'm showing pix of has some bronze colored av in it as yours looks to also, as well as what appears to be blue and silver. THe ribbons in the one I'm showing aren't really black, more of a coffee color, so is it a bronze zebra ?? I agree w/ Jeff on yours being a simple overlapping of the black ribbons onto the white base giving a "burnt" look.

Man, that's a bigun !!

Do you have a size !!

Yeah, they're beautiful marbles !!
