CROs are not generally considered collectable by radio enthusiasts unless they are very early units from the 1930s, however this is an unusual piece of equipment and its rarity and Australian origin could make it attractive to military equipment collectors.
This unit was complete and in good original condition, complete with the interconnecting cable and a copy of the manual. Its operating condition is unknown, however my view is that there would be little point in getting it working since it would probably need replacement parts and would be of limited usefulness when fixed. Far better to retain its originality and leave it as a display piece.
I no longer have this unit as I have a space problem, so can give little more detail than is on this page.
