Single lever corkscrews come in various forms but the principle of using this type of design remains the same, as follows: After the worm has been inserted fully within the cork, lowering the single arm will extract the cork.
For designs that are two part, a lever & a separate corkscrew like the Holborn lever shown to the left you'll need to hook the lever within the hole of the corkscrew.

Original Lund levers
Have lettering & crests which are normally very well defined. You might find some remains of the copper wash. Unless pitted, the metal should be fairly smooth to touch.
Are normally badly cast, rough to feel & have a lacquered gold finish. There is also very poor definition to the lettering & emblems. Don't be fooled by rust - this is part of the con!
WARNING!!!!!! BEWARE MODERN REPRODUCTIONS
It's well worth keeping your eyes peeled for different variations of badges on single levers. Here are some examples you might find.
