A couple of days ago, I found a small wooden corkscrew on ebay. It was described as having a wobbly worm, but said nothing else. There was a buy it now of 5.95, so I took a chance as the handle looked remarkably like my goodyear patent corkscrew.
It arrived yesterday, and after a gentle turn of the handle…indeed it is a 3 inch version of the 1851 patent. It is unmarked, but a neat addition! Does anyone have a marked one for sale or trade?
