RIPKEN EXPERTS: What do I have here?

[gnishiyama]

Cal Ripken experts:

What is this bat I have here? Is this a game issued bat or game-model bat?
Looking at the batman logo in between the centerbrand and barrel it looks
like a late 90's early 2000's bat.

Its a P72 bat and 34.1 ,which is the weight, is hand written on the top end of the bat.
The bat measures 35 inches. Bat has some white markings and streak
marks which can be perceived as bat rack marks or just scratches from general handling.
What are these white markings at the end of the bat?

Any help would be appreciated.
