When Smiley lets it be known that he desperately wants to own a rifle, Sergeant Flaxman promises him one if he can prove himself a responsible citizen by helping others and keeping out of trouble. The sergeant keeps score of Smiley's deeds and misdeeds by marking 'nicks' on a tree outside his father's blacksmith shop. Trouble starts brewing, however, when Smiley's father makes a bet that the boy will not be able to earn the eight nicks required to get his gun. In one of his 'misadventures,' Smiley is suspected of stealing a cache of gold and becomes a fugitive from justice after running away in shame. When the real thief is later caught, Smiley is rewarded with a .22 calibre rifle.
A number of significant, and ultimately unsuccessful, changes were made to the Smiley Gets a Gun screenplay. As Pike and Cooper (1980) note, 'The frank but affectionate view of Australia that Kimmins had revealed in Smiley was less apparent in this sequel: the direction seemed careless and the script insufficiently developed. Concessions to popular taste weakened elements of conflict present in the original film: Smiley's father was transformed from a dissipated drunk into a respectable blacksmith; signs of extreme rural poverty and racial discrimination disappeared; and the film relied for local colour on unimaginative devices such as a tame kangaroo, which Smiley now has as a pet. Furthermore, Ralph Richardson's genial eccentricities in Smiley were replaced by a heavily mannered performance from Sybil Thorndyke as Granny' (p.296).
