A couple of years ago, I picked up a corkscrew and bottle opener lot on eBay within which was an 1871 Jenner patent for his “Watch-Key, Cork-Screw, and Watch-Opener.”
It looked to be in fairly rough shape, but there were some other goodies in the lot, and the price was fair enough.

When the lot arrived, it was clear the Jenner was a little less than desired.
Or more aptly put, it was shy a few appendages…
Nicely marked on the sheath with the patent date, the Jenner should have a watch-key atop the hole though which the sheath would slide to use the corkscrews as a T pull, and on the opposite end it should have a watch-opener.
That said, according to the patent description, the watch-key is supposed to be detachable, so it would make sense that this might go missing.
Jenner’s patent description explains he was, “…making the watch-key detachable to facilitate the substitution of a new or differently sized key for a worn out or discarded one.”
And, for any of you that has ever tried to open a stubborn antique pocket watch, it is readily understood how the watch-opener might get damaged.
Interestingly, Tommy has two examples of the Jenner, one with the watch-opener angled to one side from use, and the other with the watch-opener partially broken off.
Yesterday, after a week of watching a listing on Ebay, a Jenner patent with both the watch-key and the watch-opener (and the corkscrew) was coming to a close, and given that a complete one has been on my wish list for years, I threw out a bid and hoped for the best.
And, a Louis J. Jenner patent will soon arriving on the island…
