I had to buy it. It is a copper tube affair about eight inches long. It is about half an inch in diameter at the one (open) end and tapers down to a fine point at the other (end).
I do not know how to submit a picture to this group or even much about the "What is it" thing I've seen (and ignored, I'm afraid) from time to time.
So, any help posting a "What is it" entry with picture would be appreciated.
