What antenna are you using with the set, how long is it?
The Radio Museum gives the frequency bands for the Ekco A731 as;
SW1 Band............20.88 - 22.1 MHz
SW2 Band............17.43 - 18.4 MHz
SW3 Band............14.92 - 15.75 MHz
SW4 Band............11.51 - 12.125 MHz
SW5 Band............9.33 - 9.95 MHz
SW6 Band............6.98 - 7.4 MHz
MSW Band...........2.36 - 8.0 MHz
MW Band.............520 - 1650 kHz

The radiomuseum pictures are of my home radio set.


Antenna:
======
Around 8 to 10 meters long insulated wire stretched on the RCC building rooftop. On rooftop a 4 meters long bare copper wire 18 gauge is suspended between two porcelain insulators. The wire going from radio set is attached to this suspended copper wire.
On twice occasion the thieves have stolen the shining copper wire leaving just the long wire end fed in open air on terrace.

Is a small bobbin type "coil pack" sufficient & efficient & productive enough for MW?

Any experiences anyone have had a coil pack set? Any pictures?
