You can find them pretty easily in inscr., for uninscriptables the last one which appeared was during Halloween 2009 Mausoleum bug quest, with a q12 14^st if I remember right.
Animal Fighter had it, but I don't know who has it now, he probably sold it, cause I wanted it when he had it x)
Before that, like 7+ years ago it was possible to drop them from HA chest I believe..
And there were in Pre as well (still? not sure..)
