The next machine I'm hoping to find is a "Burpilator" Norge. Can someone describe the overall era of Burpilators, what other badges the Norge wore, so I know what to look for? Usually the most recent builds are easiest to find, and I believe that Montgomery Wards "Signature" was the most common badge on Norge besides their own, but I don't know much else besides that. And what exactly was the burped water supposed to do?
