The guitar you showed is not Private Stock.So this kind of says we didn't do this on production models, so this is not original. If it was a private stock, don't they have their own serial numbers, and not ones that start with year and then number.
Private stock still have regular serial numbers. In addition, they have a private stock number on the back of the headstock, between the tuning keys.
