Anyone have any programmes from 1979? Need to know what kind of balls they used then

ie make, model, colour etc and assumed that action shots in programme would show this. If anyone could let me have scanned photo, that would be better still.
I have been asked the question by someone who is making a film which features a league game in 1979 & they want to buy / replicate a ball for authenticity.
Many thanks (I shall be logging on again about 6.30!)
