Carlo Gemelli of Italy was granted American Design Patent 184,613 for this on March 17, 1959. The title of the patent is "Bottle Opener."
The design also includes a cap lifter & as you can see, the back has a series of toasts...cheers!
This group of six double lever corkscrews, made in aluminium are all based on Carlo Gemelli's patent. They date to the 1950/60's & all of them have a handy cap lifter mouth to get that cool bottle of Bud open. As with Gemelli's original design they also carry a series of toasts on their backs.
It's very hard to find perfect examples given the paint is easily chipped, so it's worth paying extra if you find one in great condition.
I reckon the two fellows with a mustache are the toughest to track down.
All these corkscrews were originally sold in colourful boxes which rarely turn up. If you find a boxed example at a fair price, snap it up, it'll be a very good future investment.
I've enjoyed compiling this corkscrew guide, I hope it can be of assistance to you. If you'd like to get in touch it would be great to hear from you. Peter@corkscrewsonline.com
