Two pairs of clubs drawing exactly 11 years apart!

As touched on in the previous thread, North and Central had draws exactly 11 years apart. I know this had been reported on at the time of the next draw (reckon it was Ern Kolosche who pointed it out), but for those who don't know:

Round 10 1977, North and Central met on the 4th of June at Prospect and the scores were 20.5 to 19.11 at the final curtain.
11 years later in 1988, they were at Prospect again and the scores were level at the close again, North 8.9 to Central 9.3.

The next draw to occur at League level was between Glenelg and West. 2nd of June 1990 at Glenelg was the time and place; scores being 16.22 to 19.4 come final siren time.
Exactly 11 years before in Round 9 1979, West and Glenelg met on the 2nd of June at Richmond and finished on 13.15 and 12.21 respectively.

Five dates have had three draws - the two dates above, plus the 14th of May, 14th of June and 25th of July. None of those three dates involved the same pairs of clubs, nor does the other 12 dates which have had 2 draws occur on it.
