Fork does look a bit too vertical now that I see it. Regardless, as a part-out it is worth $160.
That's correct - PR10 is 531 tubing (on the main triangle only), so mid-upper 26mm range would be pretty normal.
We know this likely isn't a PX because the fork isn't 531, it's got the crown typical of the cheaper bikes.
