Over the last couple of years, I had made it point to collect the entire syroco set of corkscrews.  And, with only one exception (the broader indian) I have each variation of stain and paint, bladed worm v. wire, and direct pull v. bell.  While I will still seek out the indian which elludes me, what do I start collecting now?
 
Walker corkscrews?  Clough corkscrews? Perille? Heeley? Celluoid?  Suggestions are welcome, as long as Peter doesn’t say, pot animal corkscrews… 
 
On another note, I managed to win a walker button corkscrew for a fair price.  Hopefully it, as well as the 14 other corkscrews that are supposed to arrive soon, will arrive soon.
