Yes they did, and it looked strange to see the L2 in its red colours, along with the new grey toolkit of the G3. The G3 was indeed delayed in the UK, which is why there are so many Legend 2 models still about today as they had a long sales run.
The Tradition is still often seen for sale here on Ebay, but the older models hardly ever come up - especially the Classic Omega, which is a pity, as the Omega was a beautiful looking machine, and would have been competing with the Hoover Senior and Electrolux 500 at the time. In 1973, the E500 was a cutting edge technology vacuum, and essentially it was the first mass produced clean fan plastivac; it ushered in the plastivac era, and was the model that eventually changed the vacuum market away from the direct air system of the last 70 odd years - and many people would have preferred one of these over a cloth bag model as it was so new and different and especially over one which cost a small fortune to buy such as the Classic Omega, and especially since at that time Kirby was unheard of in the UK and not sold in shops.
