The good news is, many pipe repair people can replace a stem, to match or to your specs, at relatively low cost, priced to match the difficulty, but in this case pretty easy and not too much. The last one I had replaced was about $25 plus shipping, a nice job replacing a continually oxidizing P-Lip stem on a nice piece of briar that is a Thompson Cigar house pipe stamped "West Germany." Looks and smokes great.
