There was a series called the American Traditional series right at the end of the '90s, with poplar bodies, so those specs the chap sent you sound correct. Unfortunately, they're also very similar to the specs of any vintage-style Jazz bass!
So I don't know how to prove your dad's bass actually is an American Traditional Jazz.
To be honest, I thought all recent Fenders had the country of manufacture written on them somewhere! I'm sure all mine say Made in USA or Made in Mexico on the back of the headstock.
