There are no casting markings at all, just a P stamped on the side...
@spookdog it's a "rare" tzr belgarda 4DL head.
Matches the p stamped barrel
Not sure how rare it is. Not rare compared to the TZR SP barrel. And it's akin to a factory 3MB head.
Always Originate, Never Pirate!
The underside resembles a 3mb head. Albeit one attacked by piston rings
Think its just a 4dl TZR125R head
