not that is a confirmation .......
had a friend in 90's that had a silver MoBy and it had those marks
sorry unk MM unk exact year
i felt how light post was and bought a purple one thur magazine(internets???...meh!)
mine did not have markings
then Ringle had that recall........
i have a Post Recall part(sent/exchanged my un-cracked MoBy post)
i called US Ringle 'office....whatever'
dude on phone(total 'bro') put me on hold and went to back
he said no purple ones but had this purple/blue one
i said whatever.....will start putting some anodized blue on my bike and Ringle sent it to me
i have never seen a 'tie-dye' purple/blue one like mine EVER
will def try to post pix when i get enough posts
cheers
