Keep up the good work research is also continuing on this side of the Atlantic as well attempting to trace where these prints may have ended up after Vietnam / Taiwan. Some very interesting was discovered just last night that might offer a clue.
It is a little bit different if a U.S. military member walks up to a U.S. military run TV station on a U.S. military base and asks questions. Same for researching on former U.S. military bases around the world. If the former base is still on Federal Property and is abandoned no one will care.
You never know what your going to find till you start searching and asking questions . . . .
Robert Lia summed it up. I'm a US government employee, not just a "fan". Nothing will be closed to me nor will there be any raised eyebrows.
Remember also I'm not just searching for missing BBC material. I have no official credentials from NBC, CBS or ABC either. Or DuMont....lol.
So all is good. And to be honest, I'll be surprised if I find anything.
But if I do, I will go through proper channels to see that the material is put in safe hands. For US material I will be going through the DIMOC (Defense Imagery Management Operations Center). For UK material, I will be going through the mods on this board - in private.
No point of me stoking a fire that doesn't exist or starting silly, baseless rumors to feed the conspiracy crowd. All will be handled professionally.
As Greg says, this is more of an "inside job" so to speak, so he is probably very well placed to make these enquiries. However, I would suggest that Greg touch base with Paul V before you make first contact, just in case you need to have some kind of official BBC permission.
