Hi David,

Apparently the set was originally made for the Forest Commission Victoria, the military version was manufactured in different models, ATR4A, B, and C.

Production numbers would be relatively low, l would think less than 1000 total.

Radio Corps were busy , they built sets for the army, navy and air force.

The military version of the set could have been even smaller and lighter if they had designed it as a Morse set only. The voice AM modulated circuit was unnecessary , for the sets intended role in the jungles was relaying messages in Morse code, using a cypher .
