Those peewees were made on the 5/8" rollers versus the 3/4" for the larger ones. There are peewee rollers too, but those peewees weren't made on them. The Mylee "tankwash" run produced very similar marbles in 2009 to the 3 shown in the photo you just put up, but if they were found together with the one that has blue in it too, then they are newer than that. There were a few oxblood peewees made during the Foxfire tankwash too, but these aren't them. I haven't looked into which tankwash run it was but 2012 or newer. It is easy to ID because there was only one tankwash run that had marbles just like that with the blue too, but I haven't gone through them to refresh my memory.
