I've got one that I got just the gourd and stem by itself, never used, on Ebay. Then I ordered a meerschaum bowl for it from J.H. Lowe (J.H. Lowe Smoking Pipe Repair Parts and Supplies). Ended up sending it and the bowl to Norwood's Pipe Repair for proper fitting. I've got about $75 invested in it. It's a medium sized one.
