The Prisoner - Roband RO50 scope

[Diabolical Artificer]

Missed that VRAT reference but did find this - http://www.roband.co.uk/174-heritage.html ,which infers Roband is still going, further down the page is a Tek 500 series ripoff or maybe an authorised build. In the Prisoner episodes there are a few Tek 500 series scopes used, usually when they are mucking about with #6's mind in a faux hospital.

Thanks for those links, Andy.
