I looked into a similar question and will pass on the answer I got.
If there is a better answer, I certainly hope someone will post it.
BATF told me that a firearms export license is required to send ANY firearm out of the country. The specific item I needed to send was (and is) all the metal (including receiver) of a Winchester 1894 commerative.
The paper work accompanying the license application was nearly one inch, so the problem remains.
I expect that someone out there (perhaps like Hill Rod and Gun??) might have an export license along with their import license. If so I hope we find them!
