Arsenal V Swindon 1979

[STFC-est1879]

Hi,Guys,
Swindon fan here since the mid 70's but also a Gooner along with many local friends etc.
I'm trying to find any footage of the League Cup quarter final game away at Highbury in 1979 when Billy Tucker scored our equaliser at the clock end resulting in a 1-1 draw and a replay at the County ground a week later. Despite searching everywhere all I can find is footage of the second game at Swindon and have hit a brick wall so any ideas would be much appreciated.
