I bought a gourd calabash disaster on ebay last year with a bad stem and a broken meerschaum bowl. The bowl damage was hidden by the seller and I was able to get a partial refund. I had Mike Myers build me a new stem, ordered a new bowl from Turkey and recorked the seal to fit. The pipe was like new except it had a horrible ghost. After blowing it out with air pressure and almost a dozen salt treatments, I now own a great pipe.
Gourd calabashes smoke cool and tend to tame harsh blends. Enjoy your pipe!
