Any Abu experts?

[Debaitable]

Can anybody please help me i.d the spool that is in my, alleged 6500 mag elite, green.

Its a silver ultracast spool with 4x9x4 bearings in the spool. The reel foot number dates the reel as a '74 but i am lead to believe that ultracast spools were 80's onwards and other abu's i have had have been 4x10x4
Possibilitys i have found are -

ABU 323 – ABU 523 – ABU 823 – ABU MAG III – ABU ULTRA MAG III – ABU XLT3
From Blackdog and Rocket reel co websites

I don't know if the cage and spool seem small or if its me using the 535 too long
