Can't believe my luck. I found a TASMA jeep radio .
I have to revise my earlier thoughts , the TASMA does appear to be a amenities receiver made for the military but the jury is still out. It is quite a heavy set, finished in Khaki Green. In common with other brands of amenities sets the power source is a 6 Volt car battery. Unusually, the Tasma has a wooden case. For some reason, the Short Wave band in the set covers a narrow frequency range , maybe the Army amenities broadcast stations operated within this frequency band.
Also found another amenities set , made by Australian Sound Systems. The tags says " Supplied by
Aust.
Army amenities service " The band change is done by removing the tuning unit and turning it upside down !
I had a Stromberg-Carlson ( Aust.) amenities set years ago.

Another Aust. brand is AWA , they made a amenities set for the Aust. army and a similar set for the USAAF in Australia, reverse Lend-Lease
