I know all to well about those UK import duties charged on North American items. I have a friend that lives in the North Lincolnshire area of your fine country that I have helped with vintage two way radio equipment. A few times he was fortunate and the UK customs let the packages slip through without charge. The last time they stung him hard on a vintage American amateur radio that I acquired and shipped to him. It was made worse since it was damaged in shipment even though it was double boxed in a heavy corrugated shipping box.
