AWA built a ton of 3BZ series Coast Watcher Radios that were the common radio used at plantations and on remote islands prewar and by Australian Coast Watchers during the war. Would assume that’s what that is supposed to represent, Most of the movies of the fifties and sixties did not care that much about how realistic the props were.
Even today its common to see someone using a BC-611 HF/AM hand talkie to communicate with a BC-1000 VHF/FM Backpack radio or one of my favorites seeing someone who’s supposed to be in WW2 using a newer radio like a nineteen fifties PRC-6 handheld.
A good web site to see real coast watcher radios is:
