Yep, legit 2001 STANDARD 24.
General guide back then is if it had a maple cap, it would be a Goldtop with natural back. If it was a Standard, it would be gold all over.
Serial number isn't the cleanest looking, but I've seen worse from the factory. A "feature" of it being handwritten.
The black plastic tuner buttons are stock. The next year they would transition to the "low mass" Phase II tuners, but from '99-'01-ish, they put plastic buttons on the Phase I keys presumably to take some mass off the headstock.
The toggle might be original (it was a factory option), but likely would've had the rotary switch originally.
