Hello, I'm Materialscientist. I noticed that you made a change to an article, Os Guinness, 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) 09:04, 18 June 2020 (UTC)

Where was the part you had an issue with, it's been a while! :) Alh1969 (talk) 22:33, 25 March 2021 (UTC)
