Hello James. I think you may find it was even earlier than 1988, it could have been as early as 1986, but I am not sure. I am also not so sure why they were ever put on sale on the UK market as I do believe they were built for the export market. These cleaners, whilst every bit as good as any Electrolux at that time, offered very little advantage over other models on sale. Neither cleaner has the facility to use as a blower, something only the Slimline range was unable to do until then, and the red model you have would have had plastic tubes. But by then a good deal of Electrolux cleaners were fitted with plastic tubes, so it wasn't exactly a machine of much lesser quality.
