i used to think like that too.. but the more i see pics of the wild ones not only lewisi but of all cyclura species.. i see that there is much more variation than i first thought..

GC is Brittish and i know that they have at least shipped them to the UK.. thats fore sure.. so no i do not think they only shipped to the USA.. as Tom C said.. they could collect WC and bring them in to the states without any paperwork back in the 1960-1970.. so why not europe when the islands belonged to a European country? they where not listed back then as they are today.
