I don't know who made the first one, it could be foreign. Looks like blue AV? Master made some I believe, but not the swirly types. MK made some with heavy AV too I think. The swirl ones are still debated but mostly attributed to Champion, although that would be about the only marble they ever made with intentional AV if so, which is odd. Plus many were big for Champion. The solid black AV non-swirls could possibly be from Pelt.
