4 new stag corkscrews

I've always been a fan of stag and tusk corkscrews. These show up in a number of different shank designs and configurations. Each one is unique as stag horn is a naturally occuring product. Often sporting 1, 2, or even 3 Sterling silver end caps which are often engraved with the owner's initials. One of these is also engraved with the date 1901.
