Fujigen started making their own pickups in 1981. http://www.daeschler.com/articles/fujigen/
The Maxon pickups with the stamped serial numbers stop around this time, 1981/1982.
In the 70s and early 80s, Hoshino Gakki used Maxon pickups for Ibanez's and Kanda Shokai used Maxon pickups for Grecos. Hoshino Gakki and Kanda Shokai cooperated on many models like the Destroyer, Iceman, Artist etc.
Jim Donahue from Ibanez says that Hoshino Gakki used Maxon, Fujigen and Gotoh for pickups and Kanda Shokai would have done a similar thing so my money is on the Greco pickups from 1982 being made by Fujigen and not Maxon. In the pickup image Fujigen probably put their own Dry 1982 sticker on a Maxon Dry Z pickup.

The manufacture has changed, The winding machines have changed and also the materials probably like the wax, Plate maker and some other components have changed.
They are would the exact same with the same construction and teh same magnet and wire. Older pickups loose strength (Gause) because the magnets over time weeken. Also wax Crumbles.
So the answer is they are teh same spec but made by a different pickup maker, Ibanez used Maxxon, Gotoh and also Fuji-Gen wound pickups for them.
If you listen to say a Korean Super 58 in a AS120, You will hear that although it is made to the same spec it is not even close to the Japanese made ones.
Ibanez will proboably switch to all Korean made pickups soon because the price in Japan is so high.
