#2 is not a transitional.
With that being said; I would not call any of them “cubscouts”.
The one on the far right seems to be a Marble King made marble—maybe an “anemic “Cubscout”.
It may be the lighting that is throwing me off here but the three on the left appear to have been “veneered” over a white base glass. I will throw that aside and consider my gut which says that they are Akro Agate, intended to be corkscrews.
I appreciate all opinions and hope to see some more.
Marble—On!!
