U138’s funnel is based on German in a photograph dated 6 November 2005, although the recorded retrieval date precedes that date. The flag is sourced to the agents’ website and Ivan Sache’s FOTW image of 12 June 2009 from the company website.
Mitchell shows a “U” in dark green or possibly teal, without identifying the origin of his illustration. The U280 flag is assumed from the funnel, rather than independently documented.
