If I recall, Ferranti supplied parts of Foxhunter, and sat in store for years waiting for the GEC parts to be ready.....
Indeed they did Tuc, Not surprising seeing FMCW was something that Ferranti had been working on since 1951 (years before any other radar firm in the UK). I'd concur about Ferranti radar kit, of all the stuff I've worked on, the best. Worst bit of kit, I've ever work on for reliability was American.
