Hi Mark,

 

Have a look at the latest on my “treasures” thread.  Is this what you are looking for?

Thanks, thats the type of device I am looking for, but yet another/different design.

I have been fortunate to have tracked down someone who holds an original example –  confirmed from its part numbers, and compliance with the drawing dimensions.

It is a single 1″ diameter black “Dexine” tube that is 2′ 1″ long, with a machined steel bush (flute end) fitted at the aerial cable exit end.

It is a lot simpler than the black “Dexine” tube used in the Avro Anson that starts with the same 1″ diameter black “Dexine” tube from the reel to the floor of the Anson, but that version then has a second 1″ ID tube in place over the first (ie a double tube) for the section protruding below the aircraft, it has the same machined steel bush (flute end) but the Anson version has a Lightning shield that is fitted over the flute end.
