First, there's nothing to "pardon". Your gun got seized, and end of story. And no, 007 doesn't sell all black guns to the public, just ones with clear receivers, and you can import those yourself if you can find them outside of Canada.
As for a PAL, it means jack shit when it comes to prohibited items. You should perhaps read the Big Ol' Airsoft Q&A thread. It'll answer a lot of your questions before you even need to ask them.
