Swift Whip

I've been keeping my eye out for one of these for years because my grandmother had one when I was young and I finally found one today in an op shop. It took me nearly two hours to clean and make it like new again. The Swift Whip, a propert product made in Australia, patent ball drive, was manufactured between the 1930s and the 1980s, but the older ones had steel balls rather than plastic ones. Mine is all steel with wood handles so I figure it's between sixty and eighty years old. I love it and will be using it at every opportunity. I went on the Internet and note that there is one in the New Zealand Museum, others are being sold on Ebay. I'm not selling mine.
