I would lean towards Alley Agate here.
I do not think that Akro made this one.
It is very cool--just not Akro imho.

You are slaking--get back on the zambonie.

A jabo ("Jaybo") classic is one that was made by the factory for general sales throughout the world. Just a general marble made for production and sales.
The other Jabo are “Contract runs”. These were made in a special circumstance under the supervision of some highly qualified marble makers.
Marble collecting folks would get together—spend some money and get some special marbles out of the effort. These were all limited as to the effort placed and were never made for the worldwide market.
I hope that this helps you out.
Marble—On!!
