A few more questions for the experts

[luthier]

Hi everyone,

Need some quick help with a few rather diverse questions. Hope you guys will have some insight.

1. What were the standards for painting the insides of ship vents? Most civilians paint them red. How were they painted on German and British warships?

2. Any info on Italian radio navigation equipment installed on the BR-20? We have some, but we could use a manual, or at least a detailed descriptions of what knobs one needed to turn to do what to which gauge.

3. Same on British radio navigation equipment and direction finding. Where were the frequencies set, how were they made available to the flight crew (maps, lists, etc), who turned which knob where, etc.

4. Any info on historical radio stations operating during BoB - locations, frequencies, ranges, etc - would be nice, for both sides of the Channel.

[Edit] Couple more

5. What color were Italian torpedoes?

6. Hypothetically, let's say, a group of Spitfires is talking to the ground on 347 Khz. A German bomber over the Channel just happens to have his radio man listening to 347 KHz. Theoretically, he could he get a vector on the British squadron, right? Did something like this ever take place?
