Google is telling me to try words such as "sunflower" and "mustard and relish".
But I'm going at this blind. Never heard of these as pelt names before 90 seconds ago.
The clue I was thinking I saw was what looks like fire inside ... on the bottom of the marble.
But only comes in peewee ... no that does not make it easy for me!
Hmmmm ....

Tricky one. My first thought was actually Jabo, but I could also see it being a vintage swirl from a company such as Cairo Novelty or even a messed up Peltier. Just not sure.
