Aqua Sunbeam hand mixer

I found an Aqua Sunbeam hand mixer this weekend. It is likely a 1950 or early 1960's. The only one I found online the same was not dated but it showed up with a search for 'sunbeam 1950'. Found a great site about mixmasters: http://www.angelfire.com/home/flexibleshaft/ and another: http://www.jitterbuzz.com/indmix.html
