Got a new pipe from ebay for 8 smackers, and I'm cleaning it up(Strong Lakeland ghost of course, the world would implode if I would for once get a pipe on ebay that didn't reek of Dove soap). Not sure if you can see, but the stinger is unlike most jeantet stingers I see, and the pipe itself is only stamped "Jeantet"(Older pipe?). This is relevant because I can't remove the stinger easily at all, and have no idea if it's even removable, and don't want to use too much force since the metal looks brittle. My question is, does anyone know if this older jeantet stinger is removable, and also how would I approach removing the metal is all corroded and stuck. I believe this stem is vulcanite since it's somewhat oxidized. Should I soak it in something? If so, what? Maybe run hot water through it? Thank you for reading.
