Any ideas? The quality and construction of this one are awesome. It's just a peewee, but it stands out.

I think it might be a MK. I'm basing this off of the seams.

My thoughts as well for MK

Except that MK did not make peewees

Marble King made tons and tons of pee wees, all through their history. All types and color combinations of Rainbows and Cat Eye pee wees.

Sorry for the disinformation, as Block’s Marbles Identification and Price Guide says “none known to exist” for MK rainbows.
