Townshend Elite Rock Mk III / Rega RB300 tonearm question

Unpacked this classic from the mid 90's.  I was overseas for many years and had this lovely TT in storage.  Recently unpacked it and am now playing music with it.  The original dealer-installed Benz Glider HO still works/sounds great too

 At that time, these tables were sold with a Townshend-installed Rega RB300 tonearm mounted on Townshend's custom mount which allows for a crude VTA adjustment via a locking thumbwheel.  This table supplies RCA jacks mounted on the rear of the arm mounting board... with wiring from the arm soldered into the RCA plugs.  I recall the USA distributor at the time was in Houston TX and the tables saw their final assembly there for US sales.

Question -- for those that might remember -- was the Rega arm that Townshend installed and sold with these tables stock Rega arms with stock wiring, or was the wiring upgraded prior to installation?  I can't tell from looking at the arm.  Of course since 1983, when the RB300 was introduced, it has become well-known that the factory wiring of the arm is perhaps it's greatest weakness.

I am thinking through, for this table/arm, whether I should pursue a wiring upgrade, or whether the wiring already better-than-stock Rega.

If any seasoned analog lovers can remember, I would be very appreciative!!!
