This Magnetron was the heart of the type 271Q naval radar use to detect U boats in the battle of the Atlantic. The Magnetron was one of the most important scientific developments of WW2.
Made in 1942/43 this example came back from Canada in 2005 where it had been a naval spare part. The original cardboard box is marked "Admiralty Signals Establishment, Oldham".
As this was manufactured in living memory, it would be interesting to hear from anyone with any experience of it.
