Al Oregon

There are some Alley that are similar but I think those are Ravenswood.

Agree, and by the way, Rainbow is for MK (Marble King); Rainbo is for Peltier.

Agree - nice one!

Agree

Looks Akro to me - maybe even thin oxblood.

Might be Pelt but unsure.

I lean to Marble King. One of the "blended" types - maybe a red/orange bee blend?

Agree

Possibility of transparent swirl or maybe a slag - hard to tell as they are so dark. Maybe a backlit picture?

Agree

Agree - tipoff is yellow and red corkscrewing around the marble from top to bottom. That makes a cork - then clear and wispy white make it a popeye.

Foreign cat's-eye, if you did not already know that.

Those look to be all newer - Mexican or Asian.

Hmmmm, seams don't quite look Master. Maybe Akro.

Agree

Flames would have some yellow. This a 'basic' Dragon

Yes

The 2nd group - blue & yellow with iridescence are Vacor (marketed as Mega in US) Wave Breakers. Other one with green, blue and other colors is Vacor Hurricane. Blue & White is probably Vacor Old Fashioned. First group might also be Vacor but name escapes me. They do also look like possible newer Marble King patches but...? Bumblebee would be correct name if they were.

Agree

Right teo probably Jabo.

I agree with Steph - not a group that you would make a profit.

Great research again.

Nice

Great info and research - thanks.

There are boxes that just had National Line. Then there are some where, like the one shown, the name of the type of marbles, in this case, Rainbo, was printed between 'National' and 'Line". Like 'Sunset', etc. But, we don't call those 'NLS' so not sure where the term NLR started.
