Jaco Pastorius signature jazz bass radius

Hello friends,
I have a very simple question; when did Fender start using a 12” radius on the Jaco signature bass?
Has it always been a 12” radius, or is this a recent change?
I always thought they had a vintage 7.25” radius, since Jaco’s actual bass was a 60s model.
If they have always been 12” then I guess it’s not an issue, but if there was a change I’d like to know which year it occurred as to avoid getting the 7.25” radius version.
Thanks so much everyone.
