ID please - Transparent cobalt base with opposing reddish and yellow patch marbles

[The Nickel Guy]

 I ended up with exactly 50 of these 5/8th mibs in a somewhat older collection. An odd random number but almost makes me think that was a "count" in a original package for this batch, arriving at that total after sorting.

They very much resemble Vacor type. They were all in great condition which I thought was unusual.

I did not recognize the pattern in the Vacor named marbles, so I thought maybe they were an older version or discontinued. Having searched a lot, I give up.

I have found them elsewhere but either ID-ed wrong or not ID-ed at all.

Thanks so much.

An early version of Vacor Blue Macaw?

[Carowill]

Definitely Vacor.

Thanks so much you two. 

I assemble sets of 24 plus a shooter from asst bags and make up labels.

This is my first non set, instead it is a count.

I shall call these "Jarts" until I learn otherwise.

My net bag card or tag.

Blue Macaw always has white patch and either yellow or red/orange patch. Never the two colors together.

Very good and thanks for the response. There isn't any white patches on the 50 mibs.
