Hello Vacbear, my knowledge of the few Morphy Richards cleaners they did is very poor. My father was with the company all of his working life, even after the factories in Orpington were closed down and production taken to Mexborough. He moved my mother and I up to Doncaster in 1971. He would have known all about these cleaners. I have a strong feeling that vacuum cleaners were made by another part of the group, possibly GEC, I am not sure. So yes they were very probably made in-house if I may use that term, but possibly not by the exact same Morphy Richards part who as we knew it made the irons and so on. I think the only reason my mother never owned a Morphy Richards cleaner was because she did not need one at the time they were available. As I have said before, of the few appliances we owned, they were all Morphy Richards where possible. But after a wireless, we only had a kettle, toaster, iron, and vacuum cleaner, plus the odd heater. Anything else was not considered necessary, though he and I were singing from the same hymn sheet on electric blankets at that time as we saw the ones which came back faulty. A worrying sight.
