I have one in very good condition, already.  For anyone still searching, there is one Champagne tap not yet bid on that I found that still includes the original gimlet and cleaner.  For those of you who have tried to use a Champagne tap without the gimlet to bore the hole, you will understand the value of a properly-sized gimlet!:
