"mad MAX" (aka Yokel-Motion 1.0)

Does the bottom of the seatpost "collar" bolt not lineup with the front one?

Good spot: yes it does! Although having a circular base to the split in the seat tube isn't unique, so it may be that they just decided to make use of that existing feature?

If it were original, that would raise the possibility that this is a converted road frame. However there is no evidence of any cable guides (notably under the BB shell) nor down tube shifter mounts, so it doesn't seem likely.

Either way, it's certainly led an interesting life!

Paint will remain a secret for now...
