There was a discussion last year on a radio forum regarding ITAR. Not many people were aware that it is an American set of rules for the US only. It has no legal basis outside of the US except for items of US origin that were under an agreement. One example of this was the destruction of RT524 radios at CFB Wainright. It was cheaper to crush them than to ship back to the US.
There are exceptions to ITAR. One category that was exempt were items that were in the public domain. Could we argue that gov surplus sold to a dealer to sell to the public qualifies.
The problem with Ebay is that it is an American company that tries to apply US law worldwide. On auctions I've followed that the item is "no longer available" I used to think it was a way to avoid Ebay fees but it also gets around the Ebay shipping policy & restrictions.
Then again I've seen military radios shipped as amateur radios so maybe an optical sight could be a telescope?
