The episode of D4 called 'Approach with Caution' screened 30 January 1974 features, very momentarily, a milkman's horse (and the 'milko'). Surely this was the very end - less than 12 months - before milk deliveries by horse in Melbourne stopped. It's odd they feature so much in D4 and there's obviously a real nostalgia for them.
Gus Mercurio plays a tremendous villain in this one, too, by the way.
