Little known fact: when Williams, Kilburn and Tootill were building the SSEM (nicknamed the Baby) - https://en.wikipedia.org/wiki/Manchester_Small-Scale_Experimental_Machine https://en.wikipedia.org/wiki/Manchester_Small-Scale_Experim... - the World's first stored program computer, some of the parts they used such as switches and so on were the same as those used by the Spitfire builders because there was plenty of them around spare in wartime Britain. When the reconstruction was being built, the restorers had to track down parts from Spitfires that were no longer airworthy to be as authentic as possible.
