Andrew Nethercott Antiques has dated this piece to the 1890s.
Probably English, stag antler handle, malacca shaft and nickel and brass collars.
The shaft is held to the device by the corkscrew helix.
With the slide latch in the handle forward it can be screwed into the cork.

The mechanical pull is 1,1/4" or 32mm, leaving the cork to be easily straight pulled at the end.
In good condition, reasonable action, all original and in good working order.
As with most corkscrew canes it is in my opinion, poorly conceived as a walking stick but ok as a corkscrew,

the Achilles heel being the handle held to the shaft by the corkscrew helix, having a tendency to undo although this one stays together well enough.
I have seen no other mechanical corkscrew canes.
Length 36,3/4" or 93cm
Weight 530 grams
