Kenwood mixer?

I would like to thank kenwood chef makers for such a brilliant machine, which I Have and is 40 years old today, I bought it a Knock & Kirbys in Woolongong in 1971 it has served me very well as I am an avid cake decorator and have to make many cakes. It was bought with the proceeds from the 1st wedding cake I made, which was made by hand. the serial N0 is 410293, I hope to have it for many years to come.
