When Broadsword calls Dannyboy he pulls a chrome plated whip antenna from the side of his Wireless Set No.18. Chrome plating not very good for camouflage. The antenna was made from green painted plug together copper tubes about 12in long carried in a recess at the side of the case. The output valve in the set was an ATP4 which gave about 1 watt output, operating indoors he would have been lucky to have had a range of even a mile, let alone reach London.
In the chase at the end I think I saw a FV610.
In the early bit when Burton & Eastwood are in one of the huts, you can see in the window the reflection of the camera crew.
But as always, if it's on the box, I end up watching it. :roll:
