Does any body have any information on items in the Spelljammers setting like "Unsung, Fantastic & Perilous Expedition of Ironhelm Jones' Rock Bottom Dwarven Mining Company," a tournament adventure written by Jean Rabe for the RPGA that debuted at Gen Con in August 1990 copies are scarce because it was a limited-run RPGA tournament module released in 1990 and never widely reprinted; surviving copies are collectors' items often only in private collections or specialty auctions. Or any lost materials in the spell jammer setting?
