Not sure if anyone has ever tried purchasing footage from the National Film and Sound Archive. I was having a browse on their site recently. Although it was not a Footscray game I noticed that they have listed the full last quarter of a 1966 Round 8 match between Hawthorn and Fitzroy at the old Brunswick Street oval. I found this interesting because in 1966 both clubs finished very low on the ladder and it was the last year Fitzroy played at the Brunswick Street oval. I don't think I have seen a broadcast of a match played at the Brunswick Street ground.
I know Caveman has put up the last ten minutes of the StKilda/Footscray match at Moorabbin from the same year. It gives hope that there still might be some gems out there. Anyone dealt with the NFSA and know about availability and prices etc.
Shoutout to Caveman, too. Keep up the good work mate.
