Sturt v Norwood Unley Oval 2018 - Norwood avenge the 1969 result !

Just 2 weeks ago the Much-Improved-In-2018 Football Budget reminded fans of the 1969 Unley Oval clash between Sturt and Norwood where Sturt - leading by 46 points at 3/4 time - kicked 12.11 to 0.2 in the last quarter to win the match by 127 points. As a 8 year old Sturt boy I remember watching the replay on TV that night - now that replay would be great to see again after a 49 year gap!
Today I was at Unley Oval and eye witnessed Norwood getting their revenge. Trailing by 4 goals at 3/4 time, they kicked 13 goals to Sturt's lousy one point in the last quarter to achieve a 9 goal win and stun the home crowd. Plenty of times I've seen Sturt lead by 4 goals at quarter time and lose by 9 goals - but to lose by this margin after being 4 goals up at 3/4 time is ridiculous !
So Spelly - here come the questions...
Was Norwood's last quarter the first ever 13 goal 4th qtr at Unley?
Has a visiting team ever kicked 13 goals in a qtr at Unley before?
Has a side at any venue with a winning margin of 9 goals ever been 4 goals down at 3/4 time before?
There are lots more questions from this game but these will do for starters - thanks in advance !

-Sturt kicked 14.5 against West in Rd 22 1980, to famously tip West Torrens out of 3rd spot.  Strictly speaking, it is the first 13 goal 4th quarter at Unley.
-South kicked 13.4 in Rd 20 2006 (3rd qtr), the last time anyone kicked 13 goals in a quarter
-No, the closest was the match in this link, the 3QT score is mentioned 11:47 into it

Centrals kicked 16 straight against North at prospect a few years ago now.

Thanks Spelly - I'd forgotten about South killing us in 2006 (for obvious reasons) !!
