It would appear that's what you've got to me!
The more I look at the shape of the headstock....looks weird, could just be the angle I guess!
If he's saying that it's a full on '62, then you should get your money back based on that alone, none of that hardware is from anywhere close to that era, the body is a refinish at the very very best, but probably a generic jazz, and the neck and stamp seems dodge!
If it was me, I would pull out!
Si
Edit: WoT got there before me. Looks like some rubbish he's put together then, seeing as the 'customiser' listed it himself
