Whilst Crammond (and many other manufacturers) would have contracted to the defense forces I think it would be unlikely this type of radio would have been regular issue. This style of radio, was made by many manufacturers and used not just for marine but anywhere phone lines did not reach.
There is still a fair bit of AM activity on the 40m, 80m and 160m bands. I imagine there would be a handful of hams in your area that would be interested in playing with that kind of gear.
It could have a vibrator style power supply in it which would allow it to be run from either 12 or 24 volts DC. Typical of the era the manufacturer would have recommended an end fed type antenna and there would have been a table in the back of the manual explaining to non technical type how the antenna should be built. There would also be notes explaining how to adapt the tank coil and perhaps additional filtering. Replacing the crystals with a AD9850 type VFO/Oscillator would be a simple way to get this gear onto the ham bands.
The resale value would not be very high. I think you'd be doing really well indeed if you could extract $100 out of someone for the set.
