A Hull lot of corkscrews

During my Florida trip, I was continuously checking my bids on several lots that were coming up at auction on the day that I was traveling. While I was outbid on all but one of the lots that I was interested in, the lot that I did win ended up having a phenomenal corkscrew jewel. All of the corkscrews in the lot are keepers and many are somewhat rare and the more common ones all seem to have markings, but the crown jewel of the lot is the Charles Hull Le Presto patent located in the center of the first picture. This is the second Le Presto that I have owned and this version is nearly immaculate. For those who have never handled one of these, in order to use it, you start by pulling the pin on the side of the handle which releases the screw. Once extended you would push the handle down toward the cork which would cause the screw to spin into the cork. Once fully inserted, the pin locks the screw in place so that the cork can be extracted. It's a highly unusual mechanism which I'm sure did not work well which is why examples like this are so rare and highly sought after.
