I also love the Admiralty funnel.
Here's a little retrospective.
1. As Irving Hemlock working off Borden PEI in 1996. That's the old Harbour Development Ltd funnel mark.
2. Wearing a Soviet era funnel marking while playing a supporting role in the move K-19: The Widowmaker. She and Tamerack appear in the movie pulling a sub out of the graving dock.
3. The hammer and sickle are gone, and she is now the camera boat for the same movie. The telescoping arm could get right down to a water line view or elevate well above.
