From the April 1878 issue of New Remedies:
Barnes’ Duplex Corkscrew
It has long ceased to be thought necessary to make separate holes of different dimensions for the passage of cats and kittens through cellar doors, but until now, a corkscrew suited for a wine bottle or demijohn would hardly be thought appropriate to draw the cork of a medicine vial. Somebody named “Barnes” has revolutionized all this, judging by a three-cornered envelope and a corkscrew which have reached us, but which furnishes us no further information. If Mr. (or Miss, or Mrs.) Barnes or whoever sent us the sample will also send a cut to illustrate this novelty and tell how, where, and for ho much such corkscrews can be bought, we have no doubt that these items will interest our readers, and be productive of enormous wealth the manufacturer.
If anyone of you out there have a three-cornered envelope that contains a Barnes’ Duplex Corkscrew, I would love to see it.
Drop me a line!
