The 930 did exist in an abundant number of variants with different waveband coverage, mainly used for monitoring puposes.
Further informations:
930/12: completely self contained set with incorporated power supply and speaker.
We are very interested in further informations, about which services did make use of the different variants of this model and about the purpose of use.
Thanks Martin

Martin,
I wonder if you've discovered this site which has many
Eddystone manuals etc.?
I suppose they might be the people to help with the information.
Good luck,
John.
P.S.
Just remembered I have a bit more information with
regard to the sets made for the British Army, - when I can
dig it out!
