Extract from Robin Webb's bio
Another memorable adventure in 1964 was a trip to New Zealand to demonstrate the S3004 and S3006 DVST displays at Wellington and Auckland. I chose to drive down the North Island from Auckland to Wellington with stops to see “bubbling mud” in Rotarua amongst other things. Amalgamated Wireless Australasia had a stand at the Auckland air show. We constructed a control tower replica and fitted it with the bright displays, CCTV and a AD210 VHF direction finder indicator. The S3006 was installed and demonstrated in the control tower at Wellington airport.

The person is Norman Faulkner but on the board is a photo of the second generation Distance From Touchdown Indicator whose type number I cannot remember. We took the prototype of this device to Auckland for the NZ ATC people to play with. I don’t think it was ever sold.
