#pipe stem

I bought a pipe on ebay recently.  I was nervous because I hadn't spent that much ($50) on an estate pipe before, and worried it'd turn out to be a sham.  The chamber had more carbon cake than I'd anticipated, but I managed to ream it sufficiently.  The real problem was the stem.  I bought this pipe because I liked the rusticated bowl, but I also liked the bent stem.  Unfortunately, the stem that came with it was cracked in a couple of places, was stained, had gunk build up inside that I couldn't get out, and was really over-bitten (to the point where the mouth piece was curved inward with wear).   (Pic1)
