I recently picked up this AN6540 with receivers to put on a shelf to decorate my new house. Unfortunately, the GF doesn't like how it looks (surprise), so I'll be passing it on. However, I'm curious about the receivers on this guy - they're unlike any i've seen in other collections on the forum (I'm looking at you, bazelot!), so I'm starting to think they're post war / civilian.
The guy I got it from was an aviation enthusiast but didn't know any history behind the flight helmet. Apparently he got it in Florida 50 years ago (he said it was unissued surplus - I'd believe that considering the great condition it's in), and planned on using it for flying but it didn't fit his head. I'm thinking that he used civilian receivers and installed them himself.
Anyways, I'd like to know your thoughts before I sell it to someone else so I can be fully transparent. I'd also love to find one someday that was actually used and has a name on it.
