It's not a tiger.
I lean strongly in the stocked camp, but am never fully 100% sure on fish like this. But yeah, in the stream a long time, probably since it was a typical 10-12 incher, so, likely 2 years. Which is plenty long enough to color up and have the fins heal up a great deal.
My reasoning: No blue eye spot. No red spots, and a touch of red on the adipose is trying to come out but not strong as is typical in wild fish. Fins show evidence of past damage but the typical fray has largely healed over, leading to a smooth edged but not perfectly shaped set of fins. Black spot pattern is typical of PFBC strain but would be unusual in Penn's. But Penn's is stocked with brown trout in some sections. It is also perfectly capable of holding them over, as evidenced by the presence of wild fish throughout. As well as letting them travel, as evidenced by everyone catching occasional stockies even in non stocked sections. And the size is such that a typical stockie, with 2 years in the stream after being stocked, would be right around that size. I.e about an inch or so larger than wilds in the same year class, as hatchery growth rates for the first year outpace Penn's creek growth rates by an inch or two.
None of those factors, on their own, are reliable. But they all add up to tell the same story here. So I'll believe the story is the most likely one.
Origins may be hatchery but don't let that ruin it for you. It's a beautiful large brown trout that is well naturalized to it's environment.
