Don't try ordering from Europe until exhausting all options in the USA.

They are most likely made in the USA on the same assembly line as other Model 70's and you should be able to special order the gun through a Winchester distributor. The first person I would ask is the owner of the shop that had the rifle you saw. It is possible that the shop owner or distributor may not have it on his list and may have to make phone calls and pester Winchester until they agree to sell him one.

Other makers also produce European variations of their guns which they frequently refuse to sell on the US market (like the Ruger Mini 14's in .222 Remington).
