Thank you for liking my Wikipedia article! I wrote it after a discussion on the UBI forums that had enough technical details and sources for making an article.

The "Tilly Orifice" (I can quite see the airmen of the RAF toast to that!) war retrofitted to all Fighter Command planes from late 1940 onwards. The device falls outside the Battle of Britain period in the narrow sense, though front-line units would have it during the late autumns fights against intruding jabos.
