User talk:84.69.12.88

Hello, I'm Materialscientist. I noticed that you made a change to an article, Patent Shaft, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Materialscientist (talk) 21:29, 29 March 2023 (UTC)


 * Hi I think you made mistake. I wanted to link two pages that reference each other with agreeing statements. 84.69.12.88 (talk) 08:15, 2 April 2023 (UTC)
