Thankyou for your replies everyone. The Mini lite was used in the Millennium Falcon in Star Wars. I think it might have been used in ATC in continental Europe as well.
Should be able to use the 100 with the deicer comms. I've plenty of experience with Lemo connectors and I already have a plug - in amplifier/adaptor for a similar Racal Jetlite.
Speaking of Racal I'm amazed they stopped production of the Astrolite. It was used almost everywhere for ATC in the UK as well as abroad.
