Paolo Soprani Super Organ.

Reads like something out of a porno site ;-)
But I am being tempted by an offer, which may be too good to refuse, from a reputable repairer of such devices who is based in Sydney, Tony Peri of Reedworks by name.
Any considerations on these monstrous beasts by the worldly-wise would be very much appreciated; my knowledge is very limited.

Do you have a photo to share? I’m not sure whether I have ever seen one of these.

Sorry, no.
But Google images has several.

6-row CBA, never saw more than 5 in my life, but always wondered why there weren't more rows.

Jerry,
I've seen six-row CBAs being used by the occasional Balkan accordionist on YouTube ?

I thought my 5-row Soprani was big, this one must be weighing 30+ pounds! ?

Just make sure the bass buttons are good, I have seen Sopranis with bad bass buttons, the plastic was desintegrating and it's a big job to replace them.

The 6 row flat-B-system accordions are not just played in Balkan countries, these models are actually named Balkan models.
While having 6 rows means that all (3) rows are doubled, making note repetition easier for the 3rd row, and you have more fingering possibilities, these accordions have a flat rather than stepped keyboard. It takes a bit of getting used to, but a flat keyboard (also used on 5-row Swiss C-system accordions) does offer some advantages: 1) glissando is easier and 2) it's easier to hit all notes in a chord exactly simultaneously than on a stepped keyboard. Disadvantages are that the buttons do not protrude as much from the base plate, and using the thumb on rows other than the first row requires a bit more care in finger position.
