Well done Hal. I sent a similar request weeks ago (to the photographer) but got no response. You must have the touch.
addendum: One of the pleasures of participating in TIGHAR is the way one feels when a bunch of conflicting data gets resolved with a clear, consistent result. In a group effort, without any real coordination (other than shared interest in these forii and some gentle steering from Ric), a key photo from an unrelated website was discovered to be mis-identified. In the process, the history of an obscure military specification was nailed down, history of export sanctions dug up from 70 years ago, and a bunch of supporting photos and documents discovered.
We still don't know what was the source of 2-2-V-1, but the unknowns have been dramatically reduced. Perhaps more importantly, the assumptions have been replaced with data.
This is better than Agatha Christie or Arthur Conan Doyle.
