For info. I recently had a nice US GI Garand stock siezed by some eager- beaver "homeland security" doofus in Chicago.

The stock was en route to me from an ebay vendor. It's valuation on the export sticker was $102.
No reason was given, however the US bureaucrats refused to discuss the issue with the seller who has been very helpful. They told the seller to consult an attorney or an import/export broker. In any event they wanted $100, plus postage, to release it back to the seller.

We mutually agreed that it was'nt worth the hassle to either of us and he will abandon the stock and thus make the world a safer and better place.

The seller agreed to refund me half or the purchase price.
I have probably gotten a dozen or so stocks from ebay over the past few yrs with no difficulties. There are no Cdn restrictions on importing these stocks, nor are they on the list of restricted parts which has been promulgated on the US side. Folks should be aware that there is a chance of getting side -swiped by the fickle finger of bureaucracy when importing even an unrestricted part.
