Thanks so far.
Some years ago I bought an antique (pre 1899) revolver on GB and the seller sent it to me to Slovenia with no problems. Of course the Slovenian Customs Service held the parcel but when I presented my import gun papers and paid the duty, I received the gun.
Unfortunately, my PC crashed recently and I can't see the old emails for the details (mode of shipping,etc-) and my memory faded, and that is why I am asking here ---

Cheers,
Jani
