[edit]@Kokopelli-UK: can you please correct the source of this drawing. It is a patent drawing, so the source is not {{own}}, this would be only correct if you would hold the patent. Pechristener (talk) 18:42, 23 October 2023 (UTC)
- OK, found the patent, fixed the source and the licence. No action required. Pechristener (talk) 20:54, 23 October 2023 (UTC)
