In my effort to find more information about poison indicators and corkscrews, I ended up having an exchange with a few poison bottle collectors.  After sharing the poison indicator corkscrews in their respective collections (Mahalah Hudson patent Bell and Hall’s Devils).  One collector also shared an image of the codd pusher corkscrews in his collection.  And, within and amongst the usual suspects was this.

Marked “WONANALL” and “PATENT APPLIED FOR.” it is a really neat piece.

Anyone out there have information about the WONANALL?  Or, do you have one in your collection?
