Spectro-X Scanner

Earthbound: Victor's clicky scanner (supplying data for the Spectro-X analysis made by Kano?). The prop is made from a 1971 Braun HLD 6/61 hair-dryer, designed by Jurgen Greubel.


Earthbound Earthbound The Exiles
Kenwood food mixer Kenwood food mixer

Earthbound: Helena's drill is a battery-powered Kenwood hand mixer with a very long drill bit. Kenwood is a leading UK kitchen appliance company, and many of their products in the 1970s were designed by Kenneth Grange of the Pentagram design consultancy. Although cordless power drills existed at the time (invented by Black and Decker in 1961), they were expensive and marketed only to industry. The first widely available portable drill was from Makita in 1978.

Water analyser

Matter Of Life And Death The Testament Of Arkadia The Exiles

A water analyser seen in Matter Of Life And Death. It is also seen in The Testament Of Arkadia (in the Arkadia cave held by Anna). The water analyser is seen again (alongside Helena's drill from Earthbound and the organitron).


Guardian Of Piri Guardian Of Piri The Testament Of Arkadia The Exiles

The Organitron is a calculator-like instrument used by Koenig in Guardian Of Piri (it is named in the script, and the name is written on the end in the green label). It is also used by Victor in other episodes including The Testament Of Arkadia. It is also seen in The Exiles

Victor's scanner from The Troubled Spirit

Heat sensor

Force Of Life

A commlock-like heat sensor is seen in Force Of Life

It is a prop from The Protectors 2-part episode "WAM" (1973). In that episode it was a walkie-talkie, used by guest stars Prentis Hancock and Jill Townsend. Another guest star, Michael Sheard is aiding the series stars, and also gets to handle one. Thanks to Chris Bentley in the book Space: 1999 The Vault (2022).
