Versions without a page of their own are read from the model code sellers put in the title. Where we have too few recorded sales of a version to quote one honestly, the column shows what sellers are asking for the ones up now instead. That is a hope, not a sale, and asking prices run above what things fetch. A dash means we have neither.
