I'm trying to make out the date code. It's either F11E30 or F11G30
looks like it could be F11G30, but November 30, 2015 hasn't come yet. The G could also stand for 1997, but the P1's didn't look like that back then (old P1's were blue in color and no textured grip--they changed it around 2008).
Note that the code cannot be F11G31 because November only has 30 days.
Maybe that G is either a C (2011) or E (2013). There is definitely a top, middle, and bottom line
